Chemical analysis of tabular alumina for refractory:
Style | Chemical Index | Physical Index | |||||
Al2O3% | SiO2% | Fe2O3% | Na2O% | Volume density (g/cm3) | water absorption | apparent porosity | |
0-1mm 0-0.5mm 1-3mm 3-5mm 3-6mm 5-8mm | 99.2min | 0.1max | 0.1max | 0.4max | 3.5 | 1.5 | 5max |
200#-0 320#-0 325# | 99.1min | 0.1max | 0.1max | 0.4max | 3.5 | 1.5 | 5max |
The main properties of tabular alumina for refractory 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
