Refractory castable material 0-1mm 1-0mm tabular alumina grit
Description for tabular alumina grit:
Tabular alumina has good heat resistance and good thermal shock capabilities at bulk temperature. Crystal stepped plate shape to increase the mechanical strength of the particles; internal structure full of closed pores, high bulk density, low apparent porosity and water absorption to reduce the amount of fluid reuse production; With good physical properties such as: high heat resistance, excellent thermal shock resistance, low shrinkage and good thermal load strength, etc. Meanwhile, high purity prevents machinery damage. Hiaxu abrasives is your best choice as refractory/ceramic material and insulation materials.
Chemical analysis of refractory castable material tabular alumina grit:
| 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 |
