Hazard Information | Back Directory | [General Description]
Gray powder with an odor of H2S in moist air. | [Reactivity Profile]
STRONTIUM SULFIDE(1314-96-1) reacts vigorously with acids to release hydrogen sulfide gas. May react exothermically with oxidizing agents including inorganic oxoacids, organic peroxides and epoxides, and inorganic peroxides to generate toxic gases. | [Air & Water Reactions]
Slowly releases H2S in moist air. | [Health Hazard]
ACUTE/CHRONIC HAZARDS: Irritant to skin and tissue. Moderate fire hazard and explosion risk. | [Chemical Properties]
grey powder giving a hydrogen sulphide-like smell in the | [Preparation]
Strontium sulfide can be
prepared by the direct reaction of the elements, calcined
in an inert atmosphere, at a 1:1.05 molecular ratio:
Sr+S+heat→SrS
SrS can also be produced by the “carbothermic reduction”
of calcium sulfate, which entails the conversion of
carbon, usually as charcoal, to CO2:
SrSO4+2C→SrS+ 2CO2
This can react further:
3SrSO4+SrS→4SrO+ 4SO2
A mixture of oxide-sulfide is the result. Thus, this
type of preparation cannot be used to prepare a pure
SrS salt. | [Production Methods]
Strontium sulfide, grayish-white solid (thermodynamic Ksp 500) reactive with water to form strontium hydrosulfide, Sr(SH)2, solution. Strontium hydrosulfide is formed (1) by reaction of strontium sulfide and H2O, (2) by saturation of strontium hydroxide solution with H2S. Strontium polysulfides are formed by boiling strontium hydrosulfide with sulfur. | [Hazard]
Moderate fire and explosion risk. Irritant to
skin and tissues. | [Flammability and Explosibility]
Nonflammable |
