High Purity Stannic Sulfide SnS2 Powder CAS 1314-95-0, 99.99%

Description of Stannic Sulfide SnS2:

Tin sulfide is an inorganic compound with the chemical formula SnS. It is a gray-black solid, insoluble in water but soluble in acid. This compound usually occurs in nature in the form of tin sulfide ore.

From the point of view of physical properties, tin sulfide is a sphalerite type of crystal structure composed of Sn2+ and S2- ions. It has a molecular weight of 150.8, a melting point of 1190°C, and a boiling point of 1470°C. Tin sulfide has high hardness, high conductivity, and semiconductor properties.

From the point of view of chemical properties, tin sulfide has high stability, is insoluble in water, and is soluble in acid. It has high oxidation resistance and is not easy to oxidize under normal temperature and pressure. In addition, tin sulfide also has good thermal stability, and heating to more than 300°C began to decompose.

In addition, tin sulfide also has some special properties. It is a typical semiconductor material whose electrical conductivity decreases with increasing temperature. At the same time, tin sulfide also has good photoelectric and thermoelectric properties, which can be used to prepare solar cells, optoelectronic devices, and thermoelectric devices.

It should be noted that tin sulfide has some toxicity, and long-term exposure or inhalation may cause health problems. Therefore, appropriate protective measures should be taken during production and use to avoid direct contact with and inhalation of this compound. At the same time, in order to ensure the quality and reliability of tin sulfide, products from certified suppliers and formal channels should be selected.

What is  Stannic Sulfide SnS2 Poudre  produced?

Direct synthesis

Direct synthesis is a method of producing tin sulfide by direct reaction of metallic tin and sulfur at high temperatures. The reaction equation is:

Sn + S → SnS

This method needs to control the reaction temperature and pressure to prevent oxidation or vulcanization of metal tin. At the same time, since the reaction is exothermic, attention should be paid to controlling temperature and heat.

Tin oxide process

The tin oxide process is a method of producing tin sulfide by reacting tin oxide with sulfur at high temperatures. The reaction equation is:

SnO2 + 2S → SnS + SO2

This method needs to control the reaction temperature and atmosphere to prevent oxidation or reduction reactions. At the same time, the resulting sulfur dioxide gas needs to be treated.

Hydrogen sulfide process

The hydrogen sulfide process is a method of producing tin sulfide by reacting metallic tin with hydrogen sulfide gas at high temperatures. The reaction equation is:

Sn + H2S → SnS + H2

This method needs to control the reaction temperature and atmosphere to prevent oxidation of metal tin or decomposition of hydrogen sulfide. At the same time, care needs to be taken with the hydrogen produced.

Ion exchange method

The ion exchange method is a method of exchanging Sn4+ and S2- ions in solution by using an ion exchanger to produce tin sulfide. The method needs to control the choice of ion exchanger and reaction conditions to obtain high-purity tin sulfide.

Electrochemical method

The electrochemical method is a method to produce tin sulfide by electrolytic reduction of Sn4+ and oxidation of S2- ions. The method needs to control the composition of electrolytes and electrochemical conditions to obtain high-purity tin sulfide.
