Aluminum Oxide Nanopowder (Al2O3)
The powder consists for not less than 95% of mass a-Al2O3. About 3% in particle size are not reacted aluminum. 2% are sorbed gases (azote, hydrocarbons), water.
Physical and chemical characteristics
Powder of white colour. Powder bulk density is about 1,7 g/sm3. Basically have a-Al2O3 phase. The particles have spherical form. Specific surface area measured by BET is 35-40 m2/g. Average size of particles is ãn=40 nm, average surface size is ãs=36 nm, average mass size is ãm=54 nm. Melting temperature is 2000 C. The powder is fire and explosion safe.
Aluminum oxide powder can be used in making electro technical ceramics and composition materials.
