  • 三氧化钨制取:煅烧仲钨酸铵或钨酸得到黄色粉末状三氧化钨的纯钨化合物制取方法。 钨酸(H2WO4)在673K温度下便开始大量脱水:H2WO4—→WO3+H2O↑ 但在773~873K温度下煅烧的产物仍含有小于0.5%的水,在973~1023K温度下煅烧产物的水含量才小于0.1%。 仲钨酸铵(APT)在高于523K的温度下便可分解:5(NH4)2O·12WO3·nH2O—→12WO3+10NH3↑ +(n+5) H2O↑ 在873K温度下便可完全分解成WO3。 中国将三氧化钨分为三级,即一级、二级和三级,其纯度相应为99.95%、99.9%和99.5%。用于生产钨制品的WO3的粒度一般用松装密度 (g/cm3) 或比表面(m2/g)表示,粒度越细,松装密度越小,比表面越大。仲钨酸铵或钨酸的粒度越粗,煅烧温度越高则煅烧所得WO3的粒度也越粗。一般煅烧仲钨酸铵所得到的WO3粒度大于煅烧钨酸所得到的WO3粒度,生产中的煅烧制度需根据对产品的粒度要求来制定。 仲钨酸铵或钨酸的煅烧作业通常在回转管状煅烧炉中进行,炉管由不锈钢制成,管外用电阻丝加热,煅烧时炉管不断旋转,转速约为2.5r/min。钨酸的煅烧温度为1023~1123K,仲钨酸铵的煅烧温度为873~973K,具体煅烧温度的选择则视对产品的要求而定。 参考资料:中国冶金百科全书总编辑委员会
