摘要:
Thermostable pigments for coloring stoving lacquers, coil coat lacquers, plastics, sand granulates, lime sandstone, enamel or ceramic glazes are zinc ferrite color pigments containing from 0.01 to 0.5% by weight of lithium.
摘要:
A process for the production of rutile mixed-phase pigments comprising calcinating of a solid mixture of titanium dioxide or titanium oxide hydroxide with a dye-producing compound of a metal, in one or more directly heated, continuously operated rotary kilns, wherein in terms of material flow, air is introduced into the kiln atmosphere countercurrently to the direction of flow of the solids in the second half of the rotary kiln.
摘要:
Chromium-antimony-rutile mixed phase pigments containing from 0.01 to 0.25% by weight of lithium are surprisingly insensitive to rapid cooling and chilling and are used for coloring plastic compositions such as polyamide or ABS plastics.

摘要:
A process for the preparation of chromate-free, Cr.sub.2 O.sub.3 -containing pigments having a spinel, haematite or corundum structure comprises blending pigment-forming raw materials corresponding to the Cr.sub.2 O.sub.3 -containing pigments with from 0.5 to 10% by weight of boric acid or phosphoric acid, calculated as B.sub.2 O.sub.3 or P.sub.2 O.sub.5, respectively, and then annealing the blend whereby the chromate-free, Cr.sub.2 O.sub.3 -containing pigment is obtained.
摘要:
Coated rutile mixed phase pigments comprise a mixed phase rutile pigment having a first coating of an oxide or hydrated oxide of titanium, zirconium, tin or a mixture thereof and a subsequent coating of an oxide or hydroxide of aluminum, and those pigments exhibit an improved tendency against flocculation in lacquers hardened with acid catalysts.
