Preparation of Cristobalite-based Ceramics Using the Discarded Quartz Crucible
摘要
Abstract
Cristobalite-based ceramics were prepared using the discarded quartz crucible , kaolin, feldspar and bauxite as raw materials .The effects of batch formula and firing temperature on phase composition , microstructure , coefficient of thermal expansion and mechanical performances of cristobalite-based ceramics were investigated by XRD , SEM, thermal dilatometer and material testing machine .The results show that cristobalite-based ceramics with good mechanical performances are obtained when discarded quartz crucible 40%, kaolin 40%, feldspar 15% and bauxite 5% at 1300 ℃ for 30 min .Bending strength and coefficient of thermal expansion of cristobalite-based ceramic are 76.45 MPa and 7.16 × 10 -6℃-1 ( RT~600 ℃) ,respectively .And thermal shock resistance (△T ) is above 180 ℃.关键词
