Preparation of Cordierite–Mullite Composite Crucibles and Structure Characterization

Abstract:

Cordierite–mullite composite crucibles were prepared via high-temperature solid-state process by using burn talc, datong soil, knar clay, bentonite, quartz, feldspar and alumina as raw materials, waste porcelain powder as skeletal material. The main influencing factors such as the raw materials radio and calcination temperature were discussed. The microstructure of the sintered sample was analyzed with X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The results show that the optimal prescription was sample II (13.34 wt% of burn talc, 10.496wt% datong soil, 40.65% knar clay, 15.00wt% waste porcelain powder,10.34wt% bentonite, 2.17wt% feldspar, 1.61wt% quartz, and 6.394wt% of alumina). The optimal sintered temperature was 1380°C and the holding time was 3 hours.
