The main properties of Tabular corundum are as follows:
- The concentration of high purity Al2O3 is 99.2%min;
- Very high crystal hardness;
- Low yield, high fracture rate 2-3 times;
- High particle bulk density 3.5-3.6g/cm3
- High melting point : 2000°C
- Chemical inertness
- Good thermal shock resistance
- Excellent volume stability
- Microcracks
- High single crystal strength
