| 摘 要： | 在生产工艺相同的前提下,陶瓷材料抵抗变形的能力本质上取决于制品的化学组成、矿物组成和显微结构。瓷质卫生陶瓷自身高液相含量决定了其高变形的固有特性,始终无法从根本上解决制品变形大的问题。通过引入适量煅烧高岭土,增加莫来石、石英等晶相含量,减少玻璃相含量,降低其高温塑性形变,实现精陶质卫生陶瓷低变形特性,并得出精陶质卫生陶瓷坯体配方适宜组成。XRD研究发现实验坯体莫来石、石英等晶相显著增加;而SEM观察实验坯体的气孔率高,玻璃相减少,因而相应的变形很小。采用实验最优配方的坯体变形度小于7mm,远远低于瓷质卫生陶瓷的变形度(20～30mm),完全能够满足制造极高规整度、大尺寸卫生陶瓷制品的要求。

| Abstract: | Essentially,deformation of sanitary ware products depends on the mineral composition and microstructure of the body.Fine pottery sanitary ware contains large amounts of mullite,quartz and other crystalline phase,and only a small quantity of glass phase,which determines its low deformation characteristics that porcelain ware can not attain.In order to decrease the high-temperature plastic deformation of body,appropriate content of calcined kaolin was added in body.XRD showed the content of mullite and quartz... |
