摘　　要：研究了六偏磷酸钠对纳米ZnO在水体系中和陶瓷釉料体系中的分散作用以及纳米ZnO对陶瓷成品釉面性能的影响。采用沉降实验、粒度分析、釉料流变性、陶瓷成品光泽度和釉料始熔温度测试手段,对含纳米ZnO的水溶液、釉料和陶瓷成品进行了表征。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。釉料中含4.0%纳米ZnO的陶瓷制品,光泽度提高5.10%,烧成温度降低约15℃。The influence of sodium hexametaphosphate on the dispersion of nano-ZnO in glaze, and the effects of nano-ZnO on ceramic products were investigated in this paper. The sedimentation tests, granularity analysis, rheology of glaze, reflet of ceramic and sintering temperature were used to characterize the aqueous and glaze systems with nano-ZnO and ceramic products. The results indicate that the optimal dispersion conditions of nano-gnO in aqueous systems are as following： 0.5 % sodium hexametaphosphate, 3.0% of nano-ZnO, and pH 9 ; in glaze systems, 0.5 % of sodium hexametaphosphate, 4.0 % nano-ZnO, pH 9. For the ceramic products dispersed 4.0% of nano-ZnO glaze, the reflet is increased 5.10% and the sinter temperature is decreased 15℃.
