参照经验配方,合理选用原料,根据各氧化物的作用,调整基础釉配方,进行探索性试验。通过对比试验,确定了无铅生料透明釉为高CaO,无或少量MgO,适量ZnO、Al2O3的长石—石灰质釉,并给出了无铅生料透明釉的最佳配方。 相似文献

建筑陶瓷全抛釉砖对透明釉提出了更高的要求。本试验通过钾长石和钠长石用量的相对变化,设计了一组长石生料透明釉和一组钙生料透明釉配方,电炉中1220℃烧成。肉眼观察釉面效果,用500倍放大镜观测釉中的气孔(泡)情况。结果表明,随着釉中的钾、钠长石用量的变化,釉中显微气孔(泡)的数量与大小相应变化,对釉的透明度产生影响。 相似文献

The effects of adding iron oxide to ceramic glaze formulations were studied in this study. Iron oxide was added in different weight ratios into the reactive transparent glaze, reactive opaque glaze, and transparent glaze formulations. The iron oxide content in the glaze composition, the coloring mechanisms, the phase distributions, and surface properties at temperatures of 950–1000-1050-1200 °C in the oxidation firing medium were investigated. Scanning Electron Microscopy (SEM) to determine the microstructural and morphological characterizations of the test glazes, X-Ray Diffractometry (XRD) to determine the crystallographic properties and phases, and X-Ray Fluorescence (XRF) analyses to determine the elemental and chemical composition were performed. In addition to these, surface images were examined with Digital Microscope (DM) and Commission Internationale de l'Eclairage (CIE) L*a*b, and water absorption values were compared. In addition, taking into account environmental factors, a comparison of ceramic glazes with the same amount of waste iron oxide was also performed for same purpose. As a result of the studies, it was observed that the addition of iron oxide and/or waste iron oxide did not have a negative effect, and coloring effects on the glaze layer were observed at different rates and firing temperatures. 相似文献
