  • Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.

  • The cytotoxic effect was tested through the colorimetric assay employing 3′-[1-[(phenylamino) -carbonyl]−3,4-tetrazolium]-bis(4‑methoxy-6-nitro) benzene-sulfonic acid hydrate (XTT) by reading the absorbance at 490 nm after 3 h of incubation post treatment [28]. The absorbance is proportional to the metabolic rate of viable (live) cells.

  • The US and Canada, however, approve the use of titanium dioxide as a food additive. Canada's recent review of titanium dioxide reconfirmed its safety and pointed out that many of the toxicity studies the EU reviewed were not relevant to the safety of titanium dioxide as a food ingredient, and that the ban is based on an abundance of caution and uncertainty.

  • In addition to these three main types of titanium dioxide, there are also specialized grades that have been developed for specific applications. For example, there are grades of titanium dioxide that have been surface-treated to improve their dispersibility in liquids, making them ideal for use in inkjet inks and other liquid applications. There are also grades of titanium dioxide that have been treated to enhance their UV resistance, making them ideal for use in outdoor coatings and plastics.
  • The rutile market has been a subject of intense interest in recent years, particularly because of its widespread use in various industries. Rutile, a mineral form of titanium dioxide, is highly valued for its exceptional strength, chemical stability, and excellent refractive index. These properties make it an essential component in paints, plastics, paper, inks, and other products that require high durability and resistance to corrosion.

  • Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.

While cost is a crucial factor in any business decision, it is essential to balance cost considerations with quality and service levels. A supplier offering competitive pricing and flexible payment terms can help you achieve cost savings without compromising on product quality.
  • Quality control is a vital aspect of paint pigment factories. Rigorous testing is conducted throughout the production process to ensure the pigments meet industry standards for color strength, lightfastness, and stability. This ensures that the paints made with these pigments will retain their vibrancy over time and withstand various environmental conditions.
  • One of the key factors to consider when choosing a supplier of rutile titanium dioxide is the quality of the product. The supplier should have a reputation for providing high-quality titanium dioxide that meets industry standards. This includes ensuring that the product has a high level of purity, excellent dispersibility, and consistent particle size distribution. The supplier should also have a robust quality control system in place to monitor the production process and ensure that the product meets customer requirements.

  • An inorganic chemical, titanium dioxide is used as a dye to help products achieve a certain appearance, including whitening a product. Some experts and publications have described it as being akin to a paint primer that's used before the color is added to food in order to give products a uniform shine. Its presence is common in many items beyond Skittles including coffee creamers, cake mixes, and chewing gum. It's also used for pigment and in cosmetics manufacturing.

  • Titanium dioxide, with the chemical formula TiO2 and a specific CAS number 13463-67-7, is an essential raw material pigment widely utilized across various industries due to its exceptional optical properties, high refractive index, and excellent UV resistance. Available in bulk quantities, this 99% pure TiO2 powder serves as a vital ingredient in numerous applications, ensuring superior performance and efficiency.

  • I will now describe some typical methods of practicing my invention, whereby lithopone of any desired grade may be produced. One of the known grades of lithopone as prepared and mixed for the trade contains sev- 6o enteen per cent. of zinc sullid. To produce this grade and a by-product of hydrosulfid of sodium, for example, I proceed as follows: The usual precautions, it will be understood, mustbe taken in preparing or for insuring the purity of the several ingredients used; but these preliminaries do not require description here. Separate aqueous solutions of the following ingredients in the proportions named are prepared: zinc sulfate, one x hundred and sixty-one pounds; barium sulfid, three hundred and thirty-eight pounds, and sodium bisulfate one hundred and twenty pounds. These ingredients, it will be recognized, are readily soluble in water. The separate solutions are then mixed and the following chemical reaction at once takes place:

  • Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.

  • However, the production process of lithopone was not without its challenges. The manufacturing process involved handling hazardous chemicals and generating toxic waste, posing significant health and environmental risks. To address these concerns, factories implemented strict safety measures and invested in research to develop cleaner production methods. These efforts led to the development of new techniques that reduced waste and improved worker safety.

  • Inductively coupled plasma-optical emission spectrometry (ICP-OES) is another popular method for determining barium in TiO2. This technique uses an inductively coupled plasma to ionize the sample and then measures the intensity of light emitted by the resulting ions. ICP-OES offers high sensitivity and wide dynamic range, allowing for the detection of trace amounts of barium. It also requires specialized equipment, but its automation capabilities can reduce costs and improve efficiency.

  • This precipitate is not suitable for a pigment until it is filtered, dried, crushed, heated to a high temperature, and quenched in cold water. The second heating in a muffle furnace at 725 C produces crystals of the right optical size.

  • ② Plastics: At present, it is the second largest user of titanium dioxide pigments, accounting for about 20% of the total demand for titanium dioxide. The amount of titanium dioxide used in plastic products will vary with the use requirements, generally between 0.5% and 5%. According to data from the National Bureau of Statistics, the production of plastic products in China increased from 57.81 million tons in 2012 to 81.84 million tons in 2019, with a compound annual growth rate of 5.1%. The amount of titanium dioxide increases accordingly.

  • There are many ways we’re exposed to titanium dioxide in our everyday life. Below are the most common ways we encounter titanium dioxide. 

  • I have found that if the acid titanium cake is first slowly added to the barium sulphide solution and rapidly stirred, this discoloration will be avoided in the'sub sequent steps em loyed inthe manufacture of lithopone.

  • The North American region suffered from the excess influx of material in the market, especially from the Asian countries, in the first half of the third quarter. The quarter, however, showed signs of significant improvement with a rise in the number of offtakes. Further, the lack of labor in the US challenged the rates of production of titanium dioxide and resulted in the depletion in the level of existing inventories, pushing the titanium dioxide price graph in an upward direction.
