Our company’s AW series of α-Al₂O₃ powder is the national project achievement and has passed the national technical appraisal. It uses a unique process and possesses the characteristics of high activity, small grains and high conversion rate.

चरित्र:
Small grain size ：After calcining, the alumina can be converted into alpha size (the smallest grain size 300 nm), so that it has better sintering activity.
High activity：Using patent technology and special calcinated process to make the alumina with high sintering activity after calcining.

High conversation rate：the conversation rate varies from 92% to 99% depending on the application of the alpha alumina.
High purity : Low content of potassium and sodium (0.04 ~ 0.06%) refractory alumina powder, which makes it have higher working temperature and working strength.

अच्छी तरलता:
1. During the calcining, the microcrystalline phase patent technology is used to make the grain smaller of alpha alumina , and fill effect better in castable refractory.
2.The crystal morphology of alpha alumina has been effectively controlled, grain surface is approximate ball type or ball type.
3. The distribution of grain size is effectively controlled and optimized, so that it has excellent liquidity.
उच्च शक्ति: strong binder at high temperature , ceramic products with high strength.
