Physical and chemical properties

Cadmium sulfide, melting point: 1750°C. CAS: 1306-23-6. Molecular weight: 144.46. Density: 4.826g/cm3, there are two kinds of cadmium sulfide crystals, α-form is lemon yellow powder, β-form is orange powder. Slightly soluble in water, soluble in acid, slightly soluble in ammonia. Can be used to make fireworks, glass glaze, enamel, luminous materials, pigments.

High-purity cadmium sulfide is a good semiconductor and has a strong photoelectric effect on visible light.

It can be used to make photoelectric tubes and solar cells. The hydrogen sulfide is prepared in the acid solution of cadmium salt.


For enamel, glass, ceramic, plastic, paint coloring.

Cadmium yellow is widely used for coloring enamel, glass and ceramics. Also used in coatings and plastics industries, and also used as electronic fluorescent materials. Cadmium Yellow is suitable for coloring almost all resins and is translucent in plastics. The light-colored cadmium yellow containing zinc sulfide is used in polyethylene, and the molding processing time should be shortened as much as possible, because zinc sulfide will promote the decomposition of polyethylene plastic and turn green. Mostly used for indoor plastic products. Cadmium yellow is mixed with blue pigments to get green.
