Chromium oxide green for coatings Industry

Chromium oxide green for coatings Industry:Paint coloring: Chromium oxide green is often used as a colorant in paints to provide long-lasting and bright green colors for walls, furniture, cars, etc.

Chromium oxide green, also known as "chromium oxide", is commonly referred to as "chromium green". Dark green hexagonal crystal or amorphous powder. Melting point 2435 ℃, boiling point 4000 ℃, relative density 5.21, refractive index 2.551. Its hydrate is commonly known as "water chromium green", which is a purple amorphous crystal or a blue-green gel like structure. Insoluble in water, acid, and alkali, soluble in hot potassium bromate solution. The property is extremely stable, and there is no change even when hydrogen gas is introduced at high temperatures. Method: It is obtained by reacting sodium dichromate with sulfur, or by heating and decomposing chromium hydroxide and ammonium dichromate. Usage: Used as a pigment, organic synthesis catalyst, ceramic glaze, paint raw material, and raw material for producing chromium alloys and chromium salts.
