CALCINED ALUMINA FOR HIGH GRADE REFRACTORY MATERIALS
Calcined Alumina For Electronic Ceramics, High A Phase Alumina Content, Low Sodium, High Whiteness
It is with high a-alumina content, high melting point, high hardness value and stable crystal form. Products made of it are with high mechanical strength, good insulating property, corrosion resistance and refractory. It is suitable for unshaped refractory production. It can increase the sintered density of the castable, reduce the moisture addition of the castable, improve its fluidity, strength and lower the rate of change.
Main Technical Parameters:
| Grade | Al2O3 % ≥ | SiO2 % ≤ | Fe2O3 % ≤ | Na2O %≤ | a-phase % ≥ | Average particle size (um) |
| ALR-10G | 99.7 | 0.10 | 0.04 | 0.06 | 95 | 3.0-4.0 |
| ALR-20G | 99.7 | 0.15 | 0.04 | 0.08 | 95 | 2.0-3.0 |
| ALR-30G | 99.7 | 0.15 | 0.03 | 0.08 | 95 | 3.0-5.0 |
| ALR-40G | 99.7 | 0.15 | 0.04 | 0.08 | 95 | 2.0-4.0 |
| ALR-50G | 99.7 | 0.20 | 0.04 | 0.08 | 95 | 1.0-3.0 |
Applications:
It can used for ceramic roller, refractory castable, pure alumina
refractory filler, kiln furniture, refractory fiber, high alumina
ceramics(especially for high alumina grinding medium), mechanical
components, electronic components, high frequency insulating
ceramics and glass and ceramics glaze.
