77060; C.I. Pigment Red 107; Crimson Antimony Sulphide;Diantimony trisulfide; Needle antimony
Molecular Formula: S3Sb2
Molecular Weight: 291.52 HS
EINECS: 215-713-4
Density: 4.64 g/mL at 25 °C(lit.)
Melting Point: 550 C
Boiling Point: 1150°C
Flash Point: °C
Solubility: Insoluble (soluble in concentrated HCl and sulfides)
Safety: Poison by intraperitoneal route. Human blood and gastrointestinal system effects by
inhalation. Questionable carcinogen. Spontaneously flammable when exposed to strong oxidizers.
Flammable when exposed to heat or flame. Moderately explosive by spontaneous reaction with
chlorates, perchlorates, ClO, thallic oxide. When heated to decomposition or on contact with
acid or acid fumes it emits highly toxic fumes of oxides of sulfur and antimony. Will react with
water or steam to produce toxic and flammable vapors.
Main Application:
Antimony trisulfide is widely used in the war industry including gunpowder, glass and rubber,
matches, fireworks and friction materials and so on as the additive or catalyst, anti-blushing agent and heat-stabilizer and also as the flame-retardant synergist replacing antimony oxide.
