摘要:
Disclosed herein are pigments comprising mostly rutile TiO2, wherein the mostly rutile TiO2 consists essentially of low abrasion TiO2 particles produced by introducing a metal halide into the chloride process. Further disclosed are ink, can coatings, fibers, papers, and plastics comprising the pigment. Also disclosed herein are pigments comprising the low abrasion TiO2 pigments comprising TiO2 particles which have been further heat treated at a temperature of at least about 800° C. in an oxidizing atmosphere for a time period of at least about 1 hour.
