What is the scope of application of tin oxide SnO2 powder?

Tin oxide exists in nature in the form of cassiterite. Cassiterite is generally reddish-brown, granular or massive, and is mostly dispersed in granite. It is the main ore for refining tin. Tin oxide is stable to air and heat, insoluble in water, almost insoluble in acid or alkali solution, but soluble in hot concentrated sulfuric acid, molten caustic and potassium hydroxide, and slightly soluble in alkali metal carbonate solution. It does not react with general chemical reagents, nor does it react with nitric acid. When heated with concentrated hydrochloric acid, it slowly becomes chloride and dissolves. At high temperature, it is reduced to metallic tin under the action of hydrogen. It reacts with CO to obtain metallic tin and CO2, and the reaction is reversible. Preparation method: burning tin in air, or reacting tetravalent soluble tin salt with alkali, or reacting metal tin with concentrated HNO3 to form β-stannic acid precipitation, and then heating and dehydrating to obtain tin oxide.

Preparation method of tin oxide

There are many preparation methods of tin oxide, including solid-phase synthesis, liquid-phase synthesis and gas-phase synthesis, each of which is divided into many methods. At present, the commonly used methods include sol-gel method, co-precipitation method, electrochemical deposition method, etc.

Overview of tin oxide SnO2 powder

Tin oxide is an inorganic substance with the chemical formula SnO2. It is white, light yellow or light gray tetragonal, hexagonal or orthorhombic crystalline powder. Melting point 1630 ℃, boiling point 1800 ℃. With a density of 6.95 g/mL [1] at 25 °C, it is also an excellent transparent conductive material. It was the first transparent conductive material to be put into commercial use. In order to improve its conductivity and stability, it is often doped, such as SnO2:Sb, SnO2:F, etc.

Properties of tin oxide SnO2 powder

Tin oxide is produced by gasification and acid processes. The appearance of acid SnO2 is yellow, the appearance of gaseous SnO2 is white, the density is 7, and the melting point is 1127 degrees Celsius. Insoluble in water, dilute acid and alkali solutions. Soluble in concentrated sulfuric acid. It dissolves with alkali to generate stannate. Used in the manufacture of opaque glass, ceramic uranium and glass polishes. Cassiterite is naturally occurring and can be made by burning tin in the air.

Application of tin oxide SnO2 powder

Tin oxide is commonly used in enamel and electromagnetic materials to make opal glass, tin salts, porcelain colorants, fabric mordants and weighting agents, steel and glass polishes, and more.

Tin oxide electrodes are widely used in the optical glass and electrolytic aluminum industries at the smelting end of blast furnaces. Tin oxide electronic grade is especially suitable for the smelting of flint glass, barium flint, barium crown, heavy crown glass, etc., and will not cause pollution to the glass.

The main application of nano-tin oxide:

1. Silver-tin contact material. Silver tin oxide contact material is a new type of environmentally friendly electrical contact material that has developed rapidly in recent years. It is an ideal material to replace traditional silver cadmium oxide contacts.

2. Antistatic additives in the plastics and construction industries

3. Transparent conductive materials for flat panel and CRT (cathode ray tube) displays

4. Electrical and electronic components

5. Tin oxide electrode for smelting special glass

6. For photocatalytic antibacterial materials
