anatase tio2 pigment powder manufacturer

...

Early manufacturing processes often involved calcination of ilmenite or rutile, which were energy-intensive and sometimes produced inconsistent quality. However, with advancements in technology, manufacturers have refined their techniques to produce higher purity anatase TiO2 through methods like the sulfate process and the chloride process. These improvements have led to more efficient production and a better quality end product.

Lithopone B301, Lithopone B311 powder, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. It was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone B301, Lithopone B311 powder is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although Lithopone B301, Lithopone B311 powder has been replaced in many applications by titanium dioxide, it is still widely used in a number of products, such as water paints.
