目前生产试剂级钼酸钠的一般工艺，是将钼精矿焙烧成三氧化钼，把三氧化钼与氢氧化钠反应生成工业钼酸钠，将工业钼酸钠经过重结晶后的晶体再溶于水，加硝酸沉淀出三氧化钼的二水物，充分洗涤后进行干燥，再于７００℃的高温条件下升华，得到高纯三氧化钼，将其溶于氢氧化钠溶 The current production of reagent-grade sodium molybdate general process is roasted molybdenum oxide molybdenum trioxide, the molybdenum trioxide and sodium hydroxide reaction of industrial sodium molybdate, industrial sodium molybdate after recrystallized crystal redissolve In water, adding nitric acid precipitated molybdenum oxide dihydrate, fully washed and dried, and then sublimated at 700 ℃ under high temperature conditions, to obtain high purity molybdenum trioxide, which was dissolved in sodium hydroxide solution
