摘　　要：在传统卫生陶瓷配方体系中引入铝矾土、红柱石作为高铝原料,采用锂辉石作为助熔剂,通过原位生成莫来石晶须增强卫生陶瓷瓷胎性能。采用XRF、DTA-TG、XRD、FE-SEM、EDS等测试手段研究了铝矾土和红柱石用量对样品抗折强度、吸水率等性能的影响。结果表明:当烧成温度为1200℃,红柱石用量为18 wt%,锂辉石用量为3 wt%时,所得样品的抗折强度为111.3 MPa,吸水率为0.34%。瓷胎内部原位生成大量交织成网络状的莫来石晶须,有效提升了样品的抗折强度,与原始样品相比提高了40.1%。In this paper,bauxite and andalusite were introduced as high-alumina raw materials into the traditional sanitary ceramic formulation system,and spodumene was used as a flux,mullite whiskers were formed in situ to enhance the performance of sanitary ceramics.XRF,DTA-TG,XRD,FE-SEM,EDS and other test methods were used to study the influence of the amount of bauxite and andalusite on the flexural strength,water absorption and other properties of the sample.The results show that when the firing temperature is 1200℃,the amount of andalusite is 18 wt%,and the amount of spodumene is 3 wt%,the flexural strength of the sample is 111.3 MPa and the water absorption is 0.34%.A large number of mullite whiskers interwoven into a network are generated in-situ in the porcelain body,which effectively improves the flexural strength of the sample.Compared with the original sample,the flexural strength is increased by 40.1%.
