Bottom price 4n 99.99% High Purity Alumina Cake For Sapphire - 5N 99.999% high purity alumina – Zhanchi Detail:

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
