High Purity Tin Oxide SnO2 powder CAS 18282-10-5,99.9%

Description of Tin Oxide SnO2 Powder:

Tin oxide can be described as an organic compound that has the formula SnO2. It is a brown solid, insoluble in water but soluble in acids, bases, and some organic solvents.

Tin oxide has high electrical conductivity and light transmittance and is widely used in the fields of electronics, optics, and catalysis. It is an excellent electronic conductor that can be used to make electronic devices, solar cells, and transparent conductive films. In addition, tin oxide can also be used in the manufacture of optical materials such as optical fiber and optoelectronic devices, as well as as catalysts and gas sensors.

The physical properties of tin oxide are also very unique. Its crystal structure is tetragonal, with high symmetry and stability. With a melting point of 1470 ° C, it has high thermal stability and can be used at high temperatures. In addition, tin oxide also has a high light transmission that can pass through visible and infrared light, so it is widely used in optical materials.

The chemical properties of tin oxide are relatively stable, and it is not easy to react with other substances. However, at high temperatures, tin oxide can react with many substances, such as carbon, carbon monoxide, hydrogen, and other reactions, to produce tin and carbon dioxide, water vapor, and so on. In addition, tin oxide can react with acid to form salts and water, such as sulfuric acid, to form tin sulfate and water.

Production Method of Tin Oxide SnO2 Powder:

Tin salt method: The tin salt method is a method of producing tin oxide by the reaction of tin salts (such as tin sulfate, tin chloride, etc.) with alkali. In the process of reaction, the pH value and temperature of the solution need to be controlled. After crystallization, filtration, washing, and drying steps, high-purity tin oxide products can be obtained.

Tin oxidation method: The tin oxidation method is a method to obtain tin oxide by controlling the oxidation reaction of metal tin. Tin oxide powder can be obtained by oxidizing metal tin at a certain temperature and atmosphere. The product purity of this method is high, but the production cost is also high.

Gas phase oxidation: Gas-phase oxidation is a method to obtain tin oxide by controlling the reaction of gaseous tin and oxygen. Tin oxide powder can be obtained by reacting metallic tin with oxygen at high temperatures. The product purity of this method is high, but the production cost is also high.

Electrochemical method: The electrochemical method is a method of obtaining tin oxide by controlled electrochemical reaction. Tin oxide powder can be obtained by using tin as an anode and electrified oxidation in a certain electrolyte. The product purity of this method is high, but the production cost is also high.

Ion exchange method: It is a method of obtaining tin oxide by ion exchange reaction. The solution containing metal ions is mixed with the solution containing tin oxide ions, and an ion exchange reaction produces the tin oxide precipitation. After filtration, washing, and drying, high-purity tin oxide products are obtained.
