- Inquiry
Stannic Sulfide is an inorganic compound, the chemical formula is SnS. It occurs in rare sulfur tin mines.
Dissolve situation:
Insoluble in water and dilute acid, soluble in concentrated hydrochloric acid and decomposed at the same time.
Application: used as catalyst for reagent and hydrocarbon polymerization, electronic manufacturing industry, brake industry, etc.
Appearance: dark brown or black powder
Grain size: 10um
Purity: ≥99.5%
Chemical properties
Tin sulfide is soluble in 3~4mol/L hydrochloric acid and 2mol/L sodium hydroxide solutions. It’s going to react with hydrogen chloride when you heat it up.
Sulfide is insoluble in alkali metal sulfide and (NH4)2S, but soluble in (NH4)2S2, as the polysulfide oxidizes Sn(II) to Sn(IV) :
SnS + (NH4) 2 s2 – (NH4) 2 sns3
In addition, hot solutions of FeCl3 and CuCl2 can oxidize SnS:
4 FeCl3+ SnS – SnCl4+ 4 FeCl2+ S
4 CuCl2+ SnS – SnCl4+ 4 CuCl + S (CuCl can further compound with SnS)
Preparation :
Tin sulfide can be obtained by direct combination of single substance and is a grey crystal.
Sn + S – – SnS
If hydrogen sulfide is introduced into Sn (such as tin chloride) solution, dark brown precipitate can be obtained, which is hydrate. The hydrate is easily dehydrated and forms anhydrous material.
SnCl2+ H2S – SnS lower + 2 HCl
Black SnS were obtained by alternating electrolysis in sodium thiosulfate solution using tin and graphite as electrodes.
Anhydrous potassium thiocyanate molten to start to appear blue (about 450 ℃), slowly add tin oxide, after the reaction to continue heating for a period of time, slow cooling, the melt water processing, the filtered to get SnS [1].
SnO2+ 2 KSCN – SnS + K2S + 2 CO up + N2 up.
