摘要
探讨了微波煅烧仲钨酸铵制取三氧化钨的新工艺。实验结果表明 :经微波煅烧 4min ,仲钨酸铵的分解率为 96 .6 7% ,并通过正交实验得出微波煅烧的主要影响因素为物料重量 ,其次为煅烧时间和微波功率。在实验范围内的最佳条件为 :微波功率 6 5 0W ,煅烧时间 4min ,物料重量 10g。
The new process of calcine for ammonium paratungstate to tungsten trioxide by microwave was investigated. The results of experiment show that the maximum decomposing rate of ammonium paratungstate is 96.67% after 4 min by microwave heating. In the new calcining process, the primary influnce factor is ammonium paratungstate's weight, the secondary factors are time and microwave power. In this experiment range, the optimum conditions are that the microwave power is 650 W, the calcining time is 4 min, and the ammonium paratungstate′s weight is 10 g.
