Properties:
Varied hues of
color in line with many specifications, fine bright red powder
though in a variety of specifications. Better dispersion. Strong
covering power and tinctorial strength, a specific gravity of about
5.1, and average particle size < 1 micron. Small water
absorption, good penetrability for ultraviolet ray, more stable in
the atmosphere and under the sunlight, good light-fastness, heat
and good alkali resistance, only soluble in the hot strong
acid.
Applications:Small soft grain, easier for grinding, applied
as colorant for paint production of the coatings industry, rubber
coloring, marble production, floor terrazzo and wall painted
finish, as the colorant and filler for the production of other
ferro-containing chemical products, plastic coloring, asbestos,
varnished cloth, painted paper, leather and leather finishing
agent, and as polishing material for hardware equipment, optical
