Production Method of Nano Zirconium Dioxide Pulp ZrO2 Nanoparticles

Chemical precipitation method: Chemical precipitation is a standard method for preparing nano zirconia powder. In this method, zirconium salt solution is used as raw material. By controlling reaction conditions (such as pH value, temperature, reaction time, etc.), zirconium salt is chemically reacted to produce zirconium dioxide precipitation. The precipitate was filtered, washed, dried and ground to obtain nano-zirconia powder. 

Sol-gel method: The sol-gel method is a method of preparing nanomaterials based on liquid phase chemical reaction. Zirconium dioxide sol was obtained by mixing zirconium salt solution with an appropriate solvent, adding a reasonable amount of reducing agent and stabilizer, and heating and stirring. Nano zirconia powder was obtained after the sol was treated by gelation, drying and grinding. The sol-gel method can achieve industrial production, but the cost is high.

Gas phase method: The gas phase method prepares nanomaterials by chemical reaction of gaseous raw materials in the gas phase state. In this method, zirconium dioxide is formed by the reaction of zirconium salt gas or vapor with oxygen at high temperatures, and the resulting zirconium dioxide particles are quickly cured during cooling. The gas phase method can realize industrial production, but the equipment investment and production cost are significant.

Pyrolysis method: The Pyrolysis method is a method that uses organic matter to produce nanomaterials by pyrolysis at high temperatures. Zirconia powder was obtained by pyrolysis of zirconium-containing organic matter at high temperatures. The pyrolysis method can achieve industrial production, but the raw material cost is high and may produce toxic and harmful gases.

Laser induction method: Laser induction method uses a laser beam to irradiate liquid or gaseous raw materials to prepare nanomaterials. In this method, zirconia-containing solution or gaseous raw material is illuminated by a laser beam, and zirconia particles are generated in a transient high-temperature and high-pressure environment. The laser induction method has the advantages of high precision and efficiency, but the equipment investment is significant, and the production cost is high.
