摘要：
The GC study of the thermal decomposition of ammonium paramolybdate tetrahydrate (APM) in the solid state in a hydrogen atmosphere is reported. The evolved gas (EG) curve shows that the compound decomposes in four distinct steps within the experimental temperature range 60-640 °C. After the first dehydration step, the compound decomposes with evolution of NH3 and H2O in two successive steps leading to the formation of MoO3. The last step is the reduction of MoO3 to MoO2. © 1990.
