Production Method of Nano Aluminium Oxide Powder Al2O3 Nanoparticles:

Chemical vapor deposition: It is an essential method for preparing nanomaterials. This method uses aluminum compounds and oxygen as raw materials, and chemical reactions are carried out at high temperatures to generate nano-alumina particles. According to the different reaction conditions, nano-alumina 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, aluminum compounds are mixed with appropriate solvents, adding the proper amount of reducing agent and stabilizer, and then alumina sol is obtained after heating and stirring reaction. Nano alumina 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 method: The preparation of nano-alumina by liquid phase method usually includes hydrolysis, precipitation, crystallization and other steps. In this method, an aluminum salt solution is used as raw material, and by controlling reaction conditions (such as temperature, pH value, reaction time, etc.), aluminum salt is hydrolyzed to produce alumina precipitation. After the rain was filtered, washed, dried and ground, nano-alumina powder was obtained. 

Microemulsion method: It is a method of preparing nanomaterials using a microemulsion system as the reaction medium. The microemulsion system was formed by mixing aluminum compounds with appropriate solvents and surfactants. In the microemulsion system, aluminum-containing compounds react with oxygen to form nano-alumina particles. The alumina particles were dispersed and stabilized in microemulsion. After separation, washing and drying, nano-alumina 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.

Pulsed laser deposition: Pulsed laser deposition is a method of preparing nanomaterials by irradiating a laser beam onto a target. In this method, the aluminum-containing mark is placed in a vacuum. The plasma is cooled and solidified rapidly in a vacuum to form nano-alumina particles. The pulsed laser deposition method has the advantages of high purity and high resolution, but the equipment investment is significant, and the production cost is high.
