Name	Iron disulfide	EINECS	235-106-8
CAS No.	12068-85-8	Density	g/cm³
PSA	64.18000	LogP	1.29390
Solubility	Insoluble in water.	Melting Point	1171°C
Formula	FeS2	Boiling Point	°Cat760mmHg
Molecular Weight	119.979	Flash Point	°C
Transport Information	UN3178	Appearance	N/A
Safety	A poison by inhalation and ingestion. The powdered sulfide ignites spontaneously in air and some air-powder mixtures may be explosive. Trace carbon lowers the ignition temperature in air to 228°C and increases the sensitivity of air-dust mixtures. Heats up spontaneously and ignites with combustibles. Incompatible with water. When heated to decomposition or in reaction with acid or acid fumes it emits very toxic fumes of SO_x. See also IRON COMPOUNDS, SULFIDES, and HYDROGEN SULFIDE.	Risk Codes	R32; R36/37/38
