al2o3 nanoparticles details: 

20-30nm, 99.99%. gama

appearance white powder

COA, SEM, MSDS are available

Also alpha Al2O3 nanoparticles are available, if you need welcome to inquiry.

Application of al2o3 nanoparticles:

gama Al2O3 nanoparticles has a large specific surface, high porosity, strong heat resistance, good formability, strong surface acidity and certain surface alkalinity, and is widely used as a catalyst and a catalyst carrier. When the alumina powder particle size extends down to the nanometer level, while maintaining the excellent characteristics of the ordinary alumina powder, it exhibits optical, electrical, magnetic, thermal and mechanical properties not possessed by conventional materials, and nano-alumina. As a new functional material, it is widely used in many fields such as optics, chemical industry and special ceramics.
