摘要
分别研究了钼酸铵溶液钼含量、中和结晶温度、中和结晶终点pH对纯氧化钼制备过程中钨含量的影响,得出了中和结晶最佳的钼酸铵溶液钼含量、结晶温度、结晶终点pH值,制备出的低钨纯氧化钼的钨含量为0.0021%(质量分数)。
The influences of molybdenum content in ammonium molybdate solution,neutralization crystallization temperature,and pH value of neutralization crystallization end point on tungsten content in pure molybdenum oxide were studied.The optimum content of molybdenum in ammonium molybdate solution,crystallization temperature and pH value of crystallization end point in neutralization crystallization process were obtained,and the tungsten content of the prepared low-tungsten pure molybdenum oxide was 0.0021 wt%.
