摘　　要：在陶瓷超低温釉纳米助熔粘接剂配方研究的基础上研究了粘接剂操作性能,釉浆流动性、釉重随釉浆含水量及粘接剂用量的变化关系;研究了制得成品瓷的铅镉溶出性能。采用透射电子显微镜、X射线衍射物相分析,氮气吸附对纳米助熔剂的主要成分纳米氧化硅进行了表征,结果表明:纳米氧化硅为无定性粉体,所提供的国产"中国红"低温釉助熔粘接剂在用量为13.04%时水含量可控范围可为50.2%到51.8%,该控制范围比英国庄信万丰的控制范围更宽,在此范围可实现单个郎酒瓶(500g容积)釉重在4.25～5.00g之间,所配制的釉浆具有较好的流动性与触变性;烧制出的酒瓶铅镉溶出量符合国家标准。After formulation research of nanosized fuse-promoting adhesives of super-low-temperature ceramics glaze, operation conditions and flowability of glaze slurry as well as the dependency of glaze weight on water concentration and adhesives content were investigated. Pb and Cd dissolubility of product ceramics was evaluated. TEM, X-Ray diffraction and N2 adsorption were used to characterize nanoparticle silica, which is the main composition of the nanosized fuse-promoting adhesives. Results indicated that nanosized silica is amorphous powder. Controllable region of glaze water content for so prepared fuse-promoting adhesives of ＂China-Red＂ glaze was between 50.2 wt% to 51.8 wt%, which is wider than that of Johnson Matthey Coporation of England. In this region, glaze weight of single Lang wine bottle （500 g volume） will be in a region of 4.25 to 5.00 gram. So prepared glaze slurry possessed acceptable flowability and Thixotropy. Pb and Cd dissolubility of product ceramics meets the requirement of national standards.
