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.

Titanium dioxide, (TiO2), a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anatase. These naturally occurring oxide forms can be mined and serve as a source for commercial titanium. Titanium dioxide is odourless and absorbent. Its most important function in powder form is as a widely used pigment for lending whiteness and opacity.

The functions of lithopone in coatings: it is mainly used in water-soluble coatings (water-soluble coatings, wall coatings), blending paint as topcoat (with reasonable high paint adhesion, excellent circulation and long storage capacity), all kinds of methyl cellulose paint (can be applied to wooden furniture such as furniture and small toys) Alkali resistant coatings based on isopropyl titanate vulcanized rubber and polyurethane materials. Also because of its excellent paint adhesion, aging resistance, acid resistance and leveling, for the production of lacquered cloth color pigments look better. It can also be used in electrophoretic coating and optical guiding system software.
