The main purpose

Use 1: Used as white paint, white glass, enamel, medicine, cement, filler, mordant and fireproof coating.

Use 2: As a flame retardant, it is widely used in plastics, rubber, textile, chemical fiber, paint, paint, electronics and other industries, and also used as a catalyst and production material in the chemical industry.

Use 3: Used as high-purity reagent, mordant and light-proof agent, also used in the preparation of pigments and potassium antimony tartrate.

Use 4: Used as a flame retardant for various resins, synthetic rubber, canvas, paper, coatings, etc., as a catalyst for petrochemicals and synthetic fibers. Used in the manufacture of mordant and opalizing agent, it is the raw material for the synthesis of antimony salt. The enamel industry is used as an additive to increase the opacity and surface gloss of enamel. The glass industry is used as a decolorizing agent to replace arsenous acid. Medicine, metallurgy, military industry, etc.
