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.
Advantages
1.high purity
2.excellent thermal volume stability and thermal shock resistance
3.low porosity
4.big crystal
5.high heat resistance
6.strong mechanical strength
7.high erosion resistance
8.excellent insulating properties
9.anti -acid and anti alkali corrosion
