Molecular formula : MW : CAS :
nature : Sb2S3 precipitation is the orange-red amorphous powder. When the smaller size of the heat and into a reddish-brown. Natural mineral said stibnite (stibnite; Antimonite), is a black crystal side ramps. Density 4.62. 550 ° C melting point. Isolated from the air under a strong heating can be distilled without decomposition. Do not dissolve in water, soluble in hydrochloric acid, ammonium sulfide and sodium sulfide solution. The system for paint, fireworks and matches. Antimony trioxide can be dissolved in hydrochloric acid, and tartaric acid increases after which leads to saturation of hydrogen sulfide in the system.
