摘要

堇青石陶瓷由于其优异的力学和电学性能而得到广泛的认可，成为研究的候选材料。以高纯度标准原料为原料，在化学计量组成下，尝试了一种合成堇青石和堇青石氧化锆(5-15 wt %)的简便方法。粘结剂、润滑剂和助熔剂如聚乙烯醇、乙二醇和氢氧化钠分别以1wt %的比例加入。将粉体混合、湿磨、100℃干燥12 h，在600 ~ 1400℃不同温度下压实烧结3 h。通过XRD、FTIR、TG/DTA等研究证实，纯堇青石中仅存在堇青石相，堇青石成分中存在锆石。

Synthesis and characterization of cordierite and cordierite-zirconia by conventional approach

A wide recognition for cordierite ceramic due to its superior mechanical and electrical properties made cordierite a candidate for study. A simple approach of synthesis of cordierite and cordierite zirconia (5-15 wt %) was tried at the stoichiometric composition with standard raw material of high purity. The binder, lubricant and flux such as polyvinyl alcohol, ethylene glycol and sodium hydroxide respectively were added with 1 wt%. The powders were mixed, wet milled, dried at 100°C for 12 h, compacted and sintered at different temperatures between 600-1400°C for 3 h. The studies on XRD, FTIR and TG/DTA were carried out and the results from the studies confirmed the presence of cordierite phase alone for pure cordierite and cordierite along with zircon for cordieritezirconia compositions.
