Refractories 
1. Description
Aluminum Oxide nanopowder is a metal oxide based nanosized material that can be used in a variety of industrial applications. It can be prepared by the hydrolysis of the alkoxide of Al2O3 and calcination of particles in the presence of stabilizing agents.
2. Characteristics
It is with high hardness, high dimensional stability, high resistivity and good insulation property.
3. Application
It’s mainly used in high grade refractory products, as well as filter ceramics and polishing products and also used for additives, catalyst, coating, fine ceramics and cosmetic filler etc.
