This paper introduces the digestion technology of mechanical activation in lieu of that of alkali boiling for manufacturing tungstic acid. 本文介绍在复盐法生产钨酸中用机械活化浸取工艺代替碱煮浸取工艺的新方法。
Reagent pure phosphato-tungstic acid was prepared by reacting sodium tungstate with dis-odium hydrogen phosphate and acidifying with hydrochloric acid. 由钨酸钠与磷酸氢二钠反应，再经盐酸酸化制得了试剂级的磷钨酸。
