The effect of sintering temperature on the structure and properties of corundum/mullite ceramics

In this work, samples are prepared by adding secondary raw bauxite and some suitable amount pure silica. After dry pressing molding, using solid phase sintering method sinter them at 1380?C,1410?C,1440?C,1410?C,1500?C,1530?C, respectively. A performance of the material is characterized by using SEM and XRD, such as microscopic morphology, phase composition and the compressive strength, etc. Combining results of experiments, explore the mechanism of sintering temperature on the properties of ceramic materials.
