It is widely used in military industry, such as gunpowder, glass rubber, matches, fireworks, friction equipment, etc. as additives or catalysts, moisture-proof agents and heat stabilizers, and instead of antimony oxide as synergistic agents.

Pure antimony trisulfide is red and yellow amorphous powder, relative density is 4.12, the melting point of 550 DEG C, the boiling point of 1080-1090 DEG C: hardness: HB2-2.5?

Color and lustre:

Three amorphous antimony trisulphide the particle size, manufacturing method and production conditions are different and there are gray, black, red, yellow, brown, purple and other colors.

The ignition point:

Antimony trisulfide is easy to be oxidized in the air. That is, since the beginning of the thermal oxidation temperature depends on the particle size

 

Solubility: insoluble in water, but soluble in hydrochloric acid, and can be slowly dissolved in hot sulphuric acid. Insoluble in water and soluble in concentrated hydrochloric acid, acetic acid, alcohol, ammonium sulfate and potassium hydroxide solution. The fireworks industry with antimony sulfide into stibnite ore powder processing, black or dark gray powder, with metallic luster, insoluble in water, with a strong reduction. It is different. When the particle size is 0.1mm, it is 290 C, and the grain size is 340 C when the grain size is 0.2mm.

Prohibition of antimony sulfide and chlorate company.
