随着欧美国家对日用陶瓷铅镉溶出限量标准的提高,骨瓷等高档瓷产品使用含铅釉装饰已不能满足出口要求。为满足现实需要,对陶瓷制品进行无铅装饰是现代陶瓷发展的必然趋势。本文结合FERRO公司的无铅釉系列产品,简单介绍了骨瓷等高档瓷用低温烧成无铅釉的优势和使用要求。 相似文献

为了降低日用瓷的烧成温度,本文重点研究了实现日用瓷中温烧成的坯釉配方。通过在坯料中加入矿化剂、在釉料中加入多组元熔剂,使瓷器烧成温度降低到1230-1250℃,目前该工艺已投入生产应用:产品理化性能达到普通日用细瓷的标准。 相似文献

The objective of this work was to design a transparent glaze for matching single-crystalline anorthite porcelain. Excessive amounts of quartz were used in glaze to improve surface hardness. Technological properties including hardness and thermal shock resistance were investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies were also carried out to analyze the microstructure. The phases found in glaze were aluminosilicate glass, quartz and cristobalite crystals. The Vickers hardness of the transparent glaze was about 2.48 GPa, which was much higher than that of commercial soft glaze and was close to hard porcelain glaze due to forming dispersed crystal particles (quartz and cristobalite) in the glass matrix. Moreover, the thermal expansion coefficient of the glaze was slightly lower than that of porcelain body which was easy to produce compressive stress in glaze surface to increase the strength of porcelain. And no cracks were observed on glaze surface after heat exchange three times from 220 °C to 25 °C, presenting excellent thermal shock resistance. 相似文献

In this study, the use of pumice as an alternative fluxing agent instead of Na-Feldspar in the transparent roof tile glaze composition was investigated. The experiments were designed as a mixture experiment. According to heating microscope results, pumice was observed deforming at 850 °C and flowing at 1270 °C. Considering the properties of the pumice it is possible to use it in raw glaze (without using frit) applications instead of feldspar. Colour, brightness and hardness values of fired samples were measured. These data were analysed with MINITAB 13.0 statistical software programme. Microstructure of glaze/tile interfaces of single fired samples was studied by using a scanning electron microscope (SEM). The use of pumice in the glaze composition showed no negative effect on the colour, brightness and hardness values and decreased the flowing temperature of the glaze. It was concluded that pumice could easily replace Na-Feldspar as an alternative fluxing agent in appropriate proportions in such kind of a roof tile glaze composition without causing undesired consequences. 相似文献
