摘要
介绍了微波煅烧钼酸铵制取高纯三氧化钼的新工艺,探讨了微波加热时间、微波功率和物料重量对钼酸铵分解率的影响,并采用XRD、SEM对制得的粉末进行了表征。实验结果表明:微波可以快速煅烧钼酸铵获得高纯三氧化钼;在本实验范围内的最佳条件下,钼酸铵的分解率为99.72%;且制得的粉末物相单一、均匀、分散性好。
A new process of preparing high - purity molybdenum trioxide by means of microwave calcining ammonium molybdate was studied in this paper. Influence of the heating time, microwave power and material weight on the decomposing ratio of ammonium molybdate was investigated. The characteristics of MoO3 powders was measured by XRD and SEM. Experimental results indicated that microwave may rapidly calcine ammonium molybdate to gain high -purity molybdenum trioxide, the decomposition rate of ammonium molybdate was 99.72%. The powders possess single phase ,uniformity and excellent dispersivity.
