摘　　要：采用高温高压合的成方法,在压力2.5GPa、温度900K的条件下制备了As S合物,对制得的样品进行了XRD、SEM和EDS测试分析。结果表明:高温高压反应法快速制备了As S二元化合物,样品物相分析和微观形貌显示没有明显的晶界,整体上呈现玻璃态。样品的能谱测试分析结果显示,该非晶态化合物As和S的原子比接近于1:1。The compound of AsS was prepared by high temperature and high pressure（HTHP）,the pressure at 2.5GPa and the temperature at 900K. For the obtained samples,the XRD 、SEM and EDS were analyzed. The results showed that AsS binary compounds were prepared rapidly by HTHP. The phase and microstructure analysis of the samples showed no obvious grain boundaries and showed obvious glassy state. The energy spectrum of the samples showed that the atomic ratio of the amorphous compounds As and S was close to 1：1.
