Strontium sulfide is an inorganic chemical compound from the group of strontium sulfides.

Production and representation

Strontium sulfide can be obtained by reacting strontium sulfate with carbon.

Strontium sulfide high purity can be used in small amounts to win very easily by heating strontium carbonate at about 1000 ° C in a sufficiently strong current of hydrogen sulphide and hydrogen.

Also possible is the manufacture directly from the elements in an inert atmosphere.

Properties

Strontium sulfide, a white solid is oxidized in air and decomposes at moisture. He has a crystal structure of sodium chloride type (a = 6.020 ) with the space group Fm3m. It decomposes in acids to form hydrogen sulfide.

Use

Strontium sulfide is phosphorescent inks for ( blue-green light ) and used for hair removal.
