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:
Industrial Grade alumina powder (Sandy Alumina, Metallurgical Grade Alumina)---Metallurgical grade alumina powder
Calcined alumina--- mainly used in ceramics, refractories, glazing industries
White fused alumina--- to be used in refractory,grinding&polishing,abrasives
Tabular alumina--- used in refractory
