THE OBSCURE HISTORY OF A UBIQUITOUS PIGMENT: PHOSPHORESCENT LITHOPONE AND ITS APPEARANCE ON DRAWINGS BY JOHN LA FARGE
- One such supplier is Company A, renowned for their high-purity Lithopone with consistent particle size distribution. Their B301 and B311 grades are tailored to meet international standards, ensuring optimal performance in diverse applications. Company A's commitment to sustainability and eco-friendly practices has also earned them accolades in the industry.
Store in a cool, ventilated, dry warehouse. Should pay attention to heat and moisture. Store separately from acid products. Lightly load and unload during handling to prevent damage to the packaging. Packed in woven bags lined with polyethylene plastic bags, each bag has a net weight of 25kg. In case of fire, use water and various fire extinguishers to save.

Matter soluble in water - At present, the domestic wet zinc smelting mainly adopts the roasting-leaching-electrowinning production process, and the zinc content in the acid leaching residue is generally 8-15%, some up to 20%, and the sulfur mass fraction is 6-12%, of which sulfuric acid The root mass fraction is 15-30%, mainly in the form of 0^0 4 (in this ammoniatic environment, the leaching rate of sulfate leaching in multiple stages can reach 70%). The zinc in the acid leaching residue is mainly in the form of ZnFe 2 0 4 . In order to recover these zinc, the treatment methods are currently available in the fire method and the wet method. The fire method is the rotary kiln evaporation method (Wilz method) and the fumigating furnace evaporation method. . The wet method has hot acid leaching or high temperature pressure leaching. The fire treatment process is long, the equipment maintenance is large, the investment is high, the working environment is poor, and a large amount of coal or metallurgical coking coal is consumed, which has low efficiency and large environmental pollution. Therefore, it is usually leached by hot acid or high-pressure leaching. These methods still have the disadvantages of: 1 consumption of a large amount of acid, low leaching rate, due to the large amount of calcium sulfate, calcium sulphate and other ultrafine particles to isolate the zinc oxide particles, resulting in Electrolytic zinc enterprises are difficult to leach in acid environment, and the second weak acid leaching is not meaningful because the recovery rate is too low. 2 If leached with strong acid, although ZnFe 2 0 4 is destroyed, the leaching rate is improved, but the iron leaching rate is also high (up to 60%). The pressure of iron removal is large, and more reagents are consumed. 3 High temperature and high pressure equipment is corroded. Serious, complicated equipment investment; 4 high operating costs, poor economic returns. 5 The last slag discharged is acid leaching residue, which brings new pollution to the environment. It has to be cured and landfilled, which not only pollutes the environment, but also wastes resources.
- Titanium dioxide, a compound as ubiquitous in our daily lives as it is in the annals of science, is more than just a mere chemical substance. It is a testament to the marvels of chemistry and its profound impact on various industries. With the formula TiO2, titanium dioxide serves as a cornerstone for products ranging from paint to sunscreen, demonstrating both its versatility and importance.

- In the panoramic view of global industrialization, TIO2 factories emerge as a beacon of innovation and progress. These establishments, dedicated to the production of titanium dioxide, play a pivotal role in shaping the modern world's technological landscape. Titanium dioxide, often referred to as TIO2, is not just another chemical compound; it is a cornerstone in various industries, from paints to sunscreens, from cosmetics to solar cells.
This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.

Why all of a sudden is there so much interest in the safety of Titanium Dioxide?
Researchers from France and Luxembourg gave E171 (the much more food friendly name for Titanium Dioxide) in Europe and the United States, to lab rats in their drinking water for 100 days.
Of those rats, 40 per cent of the exposed rodents developed “preneoplastic lesions” or precancerous growths. The Titanium Dioxide also inhibited the immune systems of the rats and “accelerated” the growth of the lesions. France’s INRA agricultural research institute, which took part in the study, said in a statement.“These results demonstrate a role in initiating and promoting the early stages of colorectal cancer formation,” though it said no conclusion could be drawn about later phases of cancer, or of any danger to humans……….(not till they test it on us!!)
The results of the study were published in the Nature journal Scientific Reports.

Freshwater algae show low-to-moderate susceptibility to TiO2 exposure, with more pronounced toxic effects in the presence of UV irradiation. It has also been shown that nano-sized TiO2 is significantly more toxic to algae Pseudokirchneriella sub-capitata than submicron-sized TiO2. Hund-Rinke and Simon reported that UV irradiated 25 nm TiO2 NPs are more toxic to green freshwater algae Desmodesmus subspicatus than UV irradiated 50 nm particles, which is in agreement with Hartmann et al. UV irradiated TiO2 NPs also inactivated other algae species such as Anabaena, Microcystis, Melsoira and Chroococcus. It was demonstrated that smaller particles have a greater potential to penetrate the cell interior than submicron-sized particles and larger aggregates. Studies have shown that the amount of TiO2 adsorbed on algal cells can be up to 2.3 times their own weight.
Cheap titanium dioxide manufacturers often emerge from regions where raw materials are abundant and labor costs are lower. Countries like China, India, and Vietnam have positioned themselves as major players in the titanium dioxide market, offering competitive pricing to attract buyers worldwide. However, while cost is undoubtedly important, buyers should also consider factors such as the quality of the product, production processes, and compliance with international standards.

Why Did Europe Ban Titanium Dioxide?
Above 20%, it is recommended to replace 1 kg TiO2 with 1.3 kg of lithopone supplier 30%.
CNNC Huayuan Titanium Dioxide Co., Ltd. (hereinafter referred to as the company or CNNC TiO2 is a famous titanium dioxide manufacturer in China and a listed company on the Shenzhen Stock Exchange. Its main products are high-grade rutile titanium dioxide, which are widely used in coatings, plastics, rubber, In ink, paper and other fields, it is known as “industrial monosodium glutamate”, and its application prospects are very broad.
