High purity alumina powder, also known as alumina, with molecular weight of 102, is a white amorphous powder, commonly known as bauxite
1. Chemical corrosion resistance
2. High purity alumina with alumina content greater than 99%
3. High temperature resistance, normal use at 1600 ℃, short-term 1800 ℃
4. Resistant to sudden cooling and heat, not easy to crack
5. It is formed by grouting with high density
our company 5N 99.999% high purity alumina produced by alkoxide hydrolysis,through strict control of raw materials and production process, the high purity alumina powder has the advantages of high purity and high density
