用热力学方法分析了 α-Sialon 合成的可能性,并通过制备 Ca-α-Sialon 和 Y-α-Sialon 进行了实验验证。对合成的 Ca-α-Sialon 和 Y-α-Sialon 采用 XRD 进行了相组成分析,运用 SEM 观察了合成材料的显微形貌,发现了长柱状的 Ca-α-Sialon 晶粒。
Thermodynamic theory was used to analyze the possibility of synthesis of α-Sialon. Ca-α-Sialon and Y-α-Sialon were prepared by hot-pressing. It was proved that the thermodynamic analysis is accurate. Additionally, the phase composition and microstructure of the sintered materials were investigated by XRD and SEM. In result,the elongated columnar Ca-α-Sialon was found.
