Effect of colemanite additions on sintering, properties, and microstructure of spodumene heatproof ceramic
Source abstract
Abstract
The effect of colemanite additives on sintering and the properties and microstructure of spodumene ceramic is studied. It is found that to identify the sintering and formation processes of a higher-density structure of ceramic it is most effective to introduce colemanite in the amounts 5 – 7%. Spodumene ceramic with CLTE (9.8 – 12.9) × 10–7 K–1, heat-tolerance greater than 100 heat cycles (800°C – water), water absorption 0.7 – 5.0%, and mechanical strength under bending 33 – 44 MPa, which all obtain at the sintering temperature 1200°C, was obtained.
