Product Description
| Alumina Ceramic Introduction Industrial alumina ceramics are mainly composed of α-Al₂O₃ (tricalcium aluminate). Common purity levels include 95%, 96%, 99%, 99.5%, and 99.7%. |
Alumina Ceramic ring：
99 alumina ceramic materials are used to make high temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve sheets | |
| Alumina Ceramic Features: High compressive strength, good bending strength at room temperature.High temperature resistance (long-term use at 1500 - 1600℃, melting point ≈ 2050℃); excellent electrical insulation property. |
Alumina Ceramic Application: Alumina Ceramic can be made to Ceramic Nozzles, Ceramic Sprayers Cyclones, Ceramic Linings, Milling Systems, Ceramic Thread guides, etc. | |
