摘    要：介绍了以多相仲钼酸铵为原料，利用其热分解性质制备单相五钼酸铵的新方法．用X射线衍射分析、差热分析、热重分析、光谱分析及化学定量分析，研究了单相五钼酸铵的化学性质．结果表明，所制备的五钼酸铵在加热过程中发生热分解反应，依次生成四钼酸铵和三氧化钼

Abstract: Single phase of ammonium pentamolybdate was synthesized through the thermal decomposition of polyphase ammonium paramolybdate. XRD, DTA, TGA, spectrum and chemical analysis were employed to study its chemical properties. Results show that single phase of ammonium pentamolybdate decomposes into ammonium tetramolybdate and molybenum oxide subsequently when heated.
