Stibnite is a lead-gray mineral, usually occurring as striated prismatic crystals, that is made up of antimony sulfide (Sb2S3) and is the main ore of antimony. It often forms groups of long, shiny metallic crystals radiating out at different angles, which look like something out of a sci-fi movie. Toxicity Warning: Stibnite (antimony) is toxic ...
اقرأ أكثرANTIMONY SULFIDE presents a serious fire risk if exposed to oxidizing agents. Crystals burn with a blue flame when heated in air [Mellor 9:522 1946-47]. Emits toxic antimony and sulfur oxide fumes if heated to high temperatures. Reacts with concentrated solutions of chloric acid with incandescence [Mellor Supp. II Part I:584 1956].
