what is the composition of lithopone?

Question

it is a mix of BASO4 AND ZnS

Answer 1

Lithopone is a white pigment composed of a mixture of barium sulfate (28 - 30%) and zinc sulfide (68 - 70%) with trace amounts of zinc oxide. It is produced by precipitation through filtering, heating and quenching works. Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper. It is used as a base for lake pigment and used as a inert pigment for paint, ink and cosmetics as well as in a large range of applications in plastic industry. It is used as a filler in paper, leather, and linoleum.

Answer 2

Lithopone is a white pigment composed of a mixture of barium sulfate and zinc sulfide. It was discovered in the 1870s and proved popular because it was cheaper than other white pigments. DuPont first sold lithopone and lithopone paints when it acquired the Harrison Brothers Paint Company in 1917. Several other acquisitions in the 1920s, notably the Grasselli Chemical Company and the Krebs Pigment and Chemical Company, soon made DuPont the largest lithopone producer in the United States.

Lithopone encountered stiff competition in the 1930s from another white pigment, titanium dioxide (TiO2). Lithopone pigments were not as durable as titanium dioxide pigments, but they were much cheaper. However, improvements in TiO2 production in the 1920s lowered its cost and threatened to displace lithopone paints. Blocked by other firms' patents from marketing its own line of TiO2 pigments, DuPont purchased a TiO2 producer, the Commercial Pigments Corporation (CPC), in 1931. DuPont then merged CPC with its Krebs subsidiary to form the Krebs Pigment and Color Corporation and sold a pure TiO2 pigment under the name Ti-Pure®, while making an improved lithopone pigment, Duolith®, by mixing lithopone with TiO2. Over the next several decades DuPont gradually phased out its use of lithopone pigment in favor of TiO2.

Answer 3

Lithopone is a white pigment, a mixture of barium sulfate and zinc sulfide. It is used in interior paints and in some enamels.

Wooden artifacts are treated with zinc sulphate and barium sulfide, which undergo ion exchange reaction to form the aforementioned precipitates, which render a marble-like finish to the wooden piece.

Answer 4

lithofone is mixture of ZnS, BaSo4 and little bit ofZnO it is a white pigment
