Direct oxidation process

The direct oxidation process is a method to obtain indium tin oxide by direct oxidation of indium metal. The process uses metal indium as raw material to carry out direct oxidation reactions in oxygen or air. The specific process is as follows: the metal indium is mixed with oxygen or air, and the oxidation reaction is carried out at a certain temperature to produce indium tin oxide. This method has the advantages of a simple process and low cost, but it also has some disadvantages, such as low product purity and easy to produce a lot of dust.

Tin salt method

The tin salt process is a method to obtain indium tin oxide by reacting tin salt with an oxidizing agent. The process takes tin salts (such as tin sulfate, tin nitrate, etc.) as raw materials. The specific process is as follows: the tin salt is mixed with an oxidizer, and the reaction is carried out at a certain temperature to produce indium tin oxide. This method has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.

Solvent method

The solvent process is a method to obtain indium tin oxide by solvent extraction. The method uses indium-containing solution (such as indium chloride, indium sulfate, etc.) as raw material to obtain indium tin oxide by solvent extraction. The specific process is as follows: the indium-containing solution is mixed with the organic solvent, and the extraction reaction is carried out at a certain temperature to obtain the organic phase of indium tin oxide. This method has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.

Electrolytic method

Electrolysis is a method to obtain indium tin oxide by electrolysis of indium-containing solution. The method takes an indium-containing solution (such as indium chloride, indium sulfate, etc.) as raw material, reduces indium ions in the solution to indium metal through an electrolytic process, and then converts indium metal to indium tin oxide through an oxidation reaction. The specific process is as follows: the indium-containing solution is mixed with the electrolyte, and the electrolytic reaction is carried out in the electrolytic cell to obtain the metal indium. Then, the metal indium is mixed with oxygen or air and oxidized at a certain temperature to produce indium tin oxide. This method has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.

Chemical vapor deposition

Chemical vapor deposition is a method to obtain indium tin oxide by chemical vapor deposition. The process uses metal indium or its compounds as raw materials and reacts with oxygen or air at high temperatures to produce indium tin oxide.

Solid particles of indium tin oxide are then obtained by cooling and condensation. This method has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.
