- Fourth, since the sulfate required for the production of the present invention is provided by the acid leaching slag itself, the mass fraction of the SO/- contained in the acid leaching slag is 15% or more, and the nanometer is prepared by using the acid leaching residue as the zinc and sulfate raw material of the lithopone. Lide powder products not only realize the resource utilization of acid leaching slag, but also turn waste into treasure, and treat and improve the acidic soil of acid leaching residue to purify the environment. Low production costs and simple operation. The metathesis reaction is carried out in a low-density ammonia system (the metathesis reactant is dissolved in recovered ammonia water), and the crystal nucleus formed is smaller. It is non-toxic and safe. The ammonia solution after synthesis and separation is returned to the leaching. There is no waste water in the whole production process. The produced waste residue meets the national solid waste discharge standard for efflux, conforms to the national industrial policy, and is an environmentally friendly “green” type process.
- The primary function of titanium dioxide in paint is its ability to provide superior opacity. By effectively hiding the underlying surface, it allows fewer coats of paint to achieve the desired color intensity and uniformity. This not only reduces material costs but also shortens application time, making it an economical choice for paint manufacturers. Additionally, titanium dioxide's refractive index contributes to the brightness and cleanliness of the paint film, ensuring that colors remain vibrant and true over time.

That being said, most experts tell us that these potential health risks shouldn’t trouble us, because titanium dioxide has been used in the market for decades, and no adverse reactions have been reported by users. The bottom line is that when used correctly, titanium dioxide should be a safe ingredient that’s safe for all skin types, every day

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
In recent years, there has been growing interest in the development of novel applications for Chinese anatase titanium dioxide, such as in the field of energy storage and conversion. For example, it has been investigated as a potential electrode material for lithium-ion batteries, due to its high conductivity and stability. Furthermore, its photocatalytic activity has been explored for use in dye-sensitized solar cells, where it can help to improve the efficiency of solar energy conversion.
As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.
Likewise, the plastics industry relies heavily on titanium dioxide to enhance the appearance and durability of plastic products. With the increasing popularity of plastic packaging and consumer goods, the demand for titanium dioxide in this industry is expected to witness steady growth in the coming years. The versatility of titanium dioxide makes it a valuable additive to improve the brightness, opacity and color stability of plastic materials, ensuring improved product performance and consumer satisfaction.
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
Titanium dioxide remains in many food products in this country because of regulatory folly by the Food and Drug Administration, which allows problematic food ingredients to remain undetected and unreviewed.
When evaluating suppliers, several factors come into play
what is the colour of barium sulphate suppliers

Lithopone(CAS NO.1345-05-7) is manufactured by a process in which barium sulfide solution is prepared by reducing barite ore (BaSO4) with carbon and leaching the resulting mass.
In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”
No. The titanium dioxide we use in our toothpastes has been proven safe by health experts around the world. It is used in our toothpastes as a white colourant, in a non-nano form as defined by European regulations. It is an approved colourant in cosmetics, and we comply with all the regulations applicable to it.
What Is Titanium Dioxide?
Lithopone, also called zinc-barium white, is a very stable network molecular structure formed by the reaction of zinc sulfate and barium sulfide and calcined at high temperature. Lithopone is a white powder that is non-toxic and non-corrosive. It is insoluble in water and does not interact with hydrogen sulfide and alkali. It dissolves with acid and produces hydrogen sulfide gas.
Buff percentage refers to the amount of uncoated or partially coated titanium dioxide particles in a product. A higher buff percentage generally indicates a lower level of coating, which can impact the overall performance of the titanium dioxide. Manufacturers must carefully control this percentage to ensure that their product meets the specific requirements of their customers.
Main products are titanium dioxide LR-982, titanium dioxide LR-108, titanium dioxide LR-996, LR-895 and other products.
