Solid Crystalline Aluminum Oxide Granules Industrial 1 - 75um Size
Calcined Alumina
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
