Production Methods of Nano Titanium Dioxide Pulparticles TiO2 Nanoparticles：

Chemical vapor deposition: It is an essential method for preparing nanomaterials. This method uses titanium compounds and oxygen as raw materials, and the chemical reaction is carried out at high temperatures to produce titanium dioxide particles. According to the different reaction conditions, nano-tio2 powders with different particle sizes and morphology can be prepared. The chemical vapor deposition method has high purity and efficiency advantages, but the equipment investment is significant, and the production cost is high.

Sol-gel method: The sol-gel method is a method of preparing nanomaterials based on liquid phase chemical reaction. In this method, titanium compounds are mixed with appropriate solvents, adding a reasonable amount of reducing agent and stabilizer, and titanium dioxide sol is obtained after heating and stirring reaction. Nano titanium dioxide powder was obtained after the sol was treated by gelation, drying and grinding. The sol-gel method can achieve industrial production, but the raw material cost is high and may produce toxic and harmful gases.

Liquid phase preparation: liquid phase practice of nano titanium dioxide powder usually includes hydrolysis, precipitation, crystallization and other steps. In this method, titanium brine solution is used as raw material, and by controlling reaction conditions (such as temperature, pH value, reaction time, etc.), the titanium brine solution is hydrolyzed to produce titanium dioxide precipitation. Nano titanium dioxide powder was obtained by filtering, washing, drying and grinding the residue. 

Gas phase method: The gas phase method prepares nanomaterials by chemical reaction of gaseous raw materials in the gas phase state. This method forms titanium dioxide particles by reacting titanium-containing gas or vapor with oxygen at high temperatures. The resulting titanium dioxide particles solidify rapidly during cooling. The gas phase method can realize industrial production, but the equipment investment and production cost are significant.

Microemulsion method: It is a method of preparing nanomaterials using a microemulsion system as the reaction medium. A microemulsion system was formed by mixing titanium compounds with appropriate solvents and surfactants. In the microemulsion system, titanium compounds react with oxygen to form titanium dioxide particles. The titanium dioxide particles were dispersed and stabilized in microemulsion. After separation, washing and drying, nano titanium dioxide powder was obtained. The microemulsion method has high purity and dispersion advantages, but the raw material cost is high, and it may produce poisonous and harmful gases.
