Production Method Titanium Oxide TiO2：

Chlorination process

The chlorination process is a method of preparing titanium oxide by chlorination reaction. The method takes titanium dioxide as raw material, reacts with chlorine gas or hydrogen chloride at high temperatures to produce titanium tetrachloride, and then reacts with pure oxygen to produce titanium oxide. The advantage of chlorination is that the process is simple and easy to operate. Still, it needs to consume a lot of energy and raw materials, and the quality of raw materials is high.

Sol-gel method

Sol-gel method is a method of preparing titanium oxide by sol-gel reaction. In this method, titanium dioxide powder is mixed with alcohol solvent, and acid or alkali solution is gradually added under stirring conditions to dissolve titanium dioxide particles and form a gel. After drying, heat treatment, and other steps, titanium oxide powder was obtained. The advantage of the sol-gel method is that the titanium oxide particles prepared have higher purity and smaller particle size but need to go through multiple steps, and the cost is high.

Chemical vapor deposition

Chemical vapor deposition is a method of preparing titanium oxide by chemical vapor deposition. In this method, titanium dioxide powder is mixed with hydrogen, oxygen, and other gases, and the reaction is carried out at high temperatures to produce titanium oxide film. The advantages of chemical vapor deposition are that the titanium oxide film prepared by chemical vapor deposition has higher purity and better structural properties. Still, it requires high-temperature conditions and complex equipment, and the cost is high.

Thermal decomposition method

The thermal decomposition method is a method for preparing titanium oxide by thermal decomposition. In this method, titanium tetrachloride is thermally decomposed at high temperatures to produce titanium oxide and chlorine gas. The advantage is that the process is simple and easy to operate. Still, it needs to consume a lot of energy and raw materials and has high requirements for equipment.

Ion exchange method

The ion exchange method is a method of preparing titanium oxide by ion exchange. In this method, titanium dioxide is exchanged with a solution containing chloride ions to obtain a complex of chloride ions and titanium dioxide. After heat treatment and other steps, titanium oxide powder is obtained. The advantage is titanium oxide prepared has higher purity and smaller particle size. Still, it needs to go through multiple steps and has higher requirements for raw materials and equipment.

Hydrolysis process

The hydrolysis process is a method of preparing titanium oxide by hydrolysis reaction. In this method, titanium-containing salts are hydrolyzed in an aqueous solution to produce titanium hydroxide colloids. After heat treatment and other steps, titanium oxide powder is obtained. The advantages of the hydrolysis method are that the titanium oxide prepared has higher purity and smaller particle size. Still, it needs to go through multiple steps and has higher requirements for raw materials and equipment.
