high purity calcined alumina for fine ceramics
The products are white fine powder,featured with low sodium content,steady transition rate,good flowability,steady shrinkage
These products consist of three kinds ,the following is the details:
| product model | Al2O3 | Na2O | SiO2 | Fe2O3 | igloss | true density | grain size | apparent density | average particle size | features and application |
| YFCA-1 | 99.7 | 0.04 | 0.05 | 0.02 | 0.07 | 3.97 | 4.1 | 1.0 | 60-70 | sphere-like powder,good flowability, less shrinkage rate, designed for making ceramics fittings by hot pressing. |
| YFCA-2 | 99.6 | 0.04 | 0.05 | 0.02 | 0.07 | 3.96 | 3.2 | 0.95 | 50-70 | this model is often used for ceramics fittings by hot pressing,dry pressing such as roller stick, Water valve slice, frictional disk etc. |
| YFCA-3 | 99.7 | 0.04 | 0.05 | 0.02 | 0.07 | 3.96 | 2.5 | 0.95 | 50-70 | plate-like powder,easy to be ballmilled, designed for raw meterial of granulation, ceramic fittings by coating,iso-static pressing. |
