Raw Material
Tabular alumina is made of high quality alumina powder
Processing
It is a pure sintered alpha alumina material which is sintering at a very fast speed under the temperature of 1900℃ with very high density. It has approximately 200μm with the development of adequate hexagonal plate alpha alumina crystals.
