lithopone

[′lith·ə‚pōn]
(materials)
A white pigment produced as a filtered, heated, quenched precipitate from reaction of barium sulfide and zinc sulfide; used as a pigment for paint, ink, filled leather, paper, linoleum, oilcloth, and cosmetics. Also known as Charlton white; Griffith's white; lithophone; Orr's white; zinc baryta white; zinc sulfide white.

Since there is no effective way to detect the output index (DC) directly which has to be measured offline and normally comes out 2 hours later after the lithopone comes out of the exit, the control largely depends on the experienced worker who empirically adjusts the calcination rotary speed according to the calcination temperature.
Along with lithopone, it is also an extender with titanium dioxide.
Cadmolith colors are red and yellow lithopone cadmium sulfides and selenides with good hiding power, good resistance to light and heat, inertness, and insolubility in organic media.
has been granted a patent for a heated mixture comprised of from approximately 1% to 46% by weight of lithopone having a refractive index greater than 1.8; and from 54% to 99% by weight of a dehydroxylated kaolin, wherein when the dehydroxylated kaolin is comprised of metakaolin, the heated mixture has a GE brightness equal to or greater than 90% and a Hunter yellowness index of less than 11, and when the dehydroxylated kaolin is comprised of fully calcined kaolin, the heated mixture has a GE brightness greater than 90% and a Hunter yellowness index of less than a 7.

Tinting strength and hiding power of the pure types are double those of lithopone types and recommended for coloring film and sheet when minimum pigment content and maximum opacity are needed.
