1315-06-6 - Uses and synthesis methods
Preparation
Tin selenide can be obtained by direct combination of elemental substances:
Sn 2 Se → SnSe2
in the conventional preparation method, the heating temperature is higher than the melting point of the compound, reaching 900~950 ℃, in order to produce high purity tin selenide SnSe.
Production method
weigh stoichiometric high purity selenium and tin respectively, put them into a clean quartz ampoule, and seal them under high vacuum (about 10-5Pa). Place the ampoule in a cold furnace and slowly raise the temperature (about 50 ℃/h). When it reaches 490 ℃, stop raising the temperature and heat for 72h. Close the furnace and slowly cool the ampoule (nearly 10h) to room temperature to obtain high purity SnSe.
in the conventional preparation method, the heating temperature is higher than the melting point of the compound, reaching 900~950 ℃, in order to produce high purity SnSe.
SnSe can also be prepared by metathesis of SnS and ZnSe or CdSe at high temperature. Dark brown SnSe precipitate can also be precipitated when H2Se gas is introduced into the acidic aqueous solution of SnCl2.
