摘　　要：以钾长石、石英、漂洗黏土等为主要原料,以羟丙基甲基纤维素为坯体增强剂,通过正交实验法制备日用陶瓷坯体。在此基础上研究了原生黏土、Al_(2)O_(3)粉体添加量对坯体白度、烧成收缩、吸水率和高温抗变形性能的影响规律及作用机理。研究结果表明,当坯体配方组成为:钾长石22.8wt.%、石英27.2wt.%、漂洗黏土50wt.%、Al_(2)O_(3)外加量8wt.%,在烧成温度1300℃、保温30min条件下,所制备试样白度为86.4、烧成收缩为6.5%、吸水率为0.4%、塑性形变指数为1.45×10^(-6)mm^(-1),比未添加Al_(2)O_(3)坯体的塑性指数降低17.1%,所研制坯体在日用陶瓷领域具有潜在应用前景。Daily used ceramic bodies were prepared by orthogonal experimental method using potassium feldspar,quartz and rinsed Kaolin as the main raw materials,hydroxypropyl methylcellulose(HPMC)as a green body reinforcing agent.On this basis,the effects and mechanisms of adding contents of raw clay,Al_(2)O_(3);on whiteness,firing shrinkage,water absorption and high tem-perature deformation resistance ability of ceramic bodies were investigated.The results show that when the body formula batch is as follows,potassium feldspar 22.8 wt.%,quartz 27.2 wt.%,rinsed clay 50 wt.%,additional Al_(2)O_(3),8 wt.%,under firing tempera-ture of 1300℃and soaking time of 30 min,the as-prepared ceramics body has whiteness 86.4,firing shrinkage 6.5%,water absorption 0.4%,and the plastic deformation index 1.45×10^(-6)mm^(-1),which reduces the plasticity index by 17.1%compared with the body without Al_(2)O_(3).The developed body has potential application prospects in the field of domestic porcelain.
