Raw material and process of production:
refractory grade calcined alumina and activated alumina sub-powder, ceramic grade alumina powder is calcined
Calcination, the activity of the calcination temperature is lower, not such a high conversion rate, other indicators are not much worse
That is not to say, some manufacturers demand for calcined to refractoriness good, and some activity needs to begood, but in refractory or more with the calcined
Application:
1. Various abrasives, abrasive tools and abrasive fillers.
2. To produce all kinds of calcined alumina fine powder for ceramic industry and refractory industry.
3. High alumina structural ceramic products
4. Electronic components, high insulating ceramic and etc.
Fetures
1. Stable crystal form
2. High hardness
3. Good resistance to abrasion
4. High mechanical strength
5. High melting point 6. Excellent electric insulating property
7. Outstanding resistance to corrosion
