摘　　要：研究了六偏磷酸钠对纳米ZnO在水中和陶瓷釉料中的分散性以及纳米ZnO对陶瓷成品性能的影响。采用沉降实验、粒度分析、釉料流变性、陶瓷成品光泽度、烧成温度测试手段,对含纳米ZnO的水溶液、釉料和陶瓷成品进行表征。结果表明,在实验条件下,纳米ZnO在水中最佳分散条件为:0.5%六偏磷酸钠,3.0%纳米ZnO,pH为9。在陶瓷釉料中最佳分散条件为:0.5%六偏磷酸钠、4.0%纳米ZnO、pH为9、陶瓷基釉200 mL。以此釉料烧成的陶瓷制品,使光泽度提高7.14%,烧成温度降低约15℃。The influenced of sodium hexame taphospha on the dispersion of nano-ZnO in glaze,and its effects on chinaware products were investigated,in which sedimentation test,granularity analysis,rheology of glaze,reflet of chinaware and sintering temperature were used to characterize the aqueous and glaze systems with nano-ZnO and chinaware products.The results indicated that the optimal dispersion conditions of nano-ZnO in aqueous systems are as follows 0.5 wt% sodium hexame taphospha,3.0 wt% of nano-ZnO,and pH=9.And in glaze systems,0.5 wt% of sodium hexame taphospha 4.0 wt% nano-ZnO,pH 9 and 200 mL of glaze.The top-quality sintered chinaware products dispersed nano-ZnO glaze,the product reflet of was increased 7.14 %,the sinter temperature was decreased 15℃.
