通过以高岭土、活性碳及Ｆｅ（ＮＯ３）３·９Ｈ２Ｏ（少量）催化剂混合物制成小圆饼样品，进行了在氮气（Ｎ２）氛中经碳热还原氮化反应合成高纯β－Ｓｉａｌｏｎ粉料的探索研究。用Ｘ射线物相分析法对反应生成物的物相组成及其相对含量进行测定，分析研究混合原样中碳与高岭土的比例、保温温度、保温时间和样品孔隙率等实验因素对合成产物组分的影响。本文讨论了有关实验条件与产物中物相的关系和β－Ｓｉａｌｏｎ的形成过程。研究结果表明，虽然实验工艺因素对合成产物的影响很复杂，直接影响着生成物中的物相及其相对含量的变化，但得到合成高纯β－Ｓｉａｌｏｎ粉料的最佳条件是可能的。
A sample of donut was made from a mixture of kaolin, activated carbon and Fe (NO3) 3 · 9H2O (small amount), and a high-purity β-Sialon powder was synthesized by carbothermal reduction nitridation in a nitrogen atmosphere Exploring research. The phase composition and the relative content of the reaction product were determined by X-ray phase analysis. The effects of experimental factors such as the ratio of carbon to kaolin in the mixed sample, holding temperature, holding time and sample porosity were studied. Impact. This paper discusses the relationship between the experimental conditions and the product phase and the formation of β-Sialon. The results show that although the influence of experimental process factors on the synthesis products is very complicated, which directly affects the phase and relative content of the product, it is possible to obtain the optimum conditions for the synthesis of high-purity β-Sialon powder.
