中文摘要：
在铝质瓷中滑石引入量一般小于5wt.%，起到简单的助熔作用，而在镁质瓷中滑石用量为65wt.%~75wt.%，在瓷体中生成均匀分散的原顽火辉石、堇青石晶粒，对整个瓷胎起到弥散增强的作用。实验通过研究1330℃下铝质瓷中滑石的用量对铝质瓷的烧结性能、抗折强度的影响，并通过XRD测试技术分析高强铝瓷的相组成。结果表明：在烧制温度1330℃下，当外加滑石用量为15wt.%时，滑石在铝质瓷烧制过程中不仅起到良好的助熔作用，而且在高温下与坯体反应生成均匀分布的原顽火辉石细小颗粒，对瓷胎起到弥散增强，有助于铝质瓷力学性能的提高。
英文摘要：
In general, a dosage of less than 5wt.%talc in alumina ceramic can help lfuxing, but in magnesia porcelain the talc dosage is 65wt.%~75wt.%. It can generate evenly dispersed protoenstatite and cordierite grains and thus dispersion strengthening the porcelain body. In the experiment, the effects of the talc dosage on the sintering properties and lfexural strength of alumina porcelain sintered at 1330℃were studied, and the phase composition of high strength aluminum porcelain was analyzed through XRD. Results show that when sintered at 1330℃, a dosage of 15wt.%talc not only produced very good lfuxing effect, but also reacted with the porcelain body and generated in it evenly-distributed tiny protoenstatite particles, which could reinforce the porcelain body and improve the mechanical properties of alumina porcelain.
