钼酸铵生产技术发展现状

摘要

Ammonium molybdate can be used as the precursor for molybdenum powder and molybdenum products.lt is also widely applied in chemical reagents,catalysts,flame retardants,and drugs etc..Variety .production situation,and technology of ammonium molybdenum at home and abroad were briefly reviewed.Technical innovations, such as application of surfactants , improvement of vapor equipment, introduction of continuous crystallizer, adoption of cycle extraction-stripping method, and addition of lixiviating agent for the preparation technology of ammonium molybdate in recent years were introduced in detail.%钼酸铵可用作生产钼粉、钼金属制品的前驱体,可广泛用作化学试剂、催化剂、阻燃剂及药物等.简要介绍了钼酸铵的品种,国内外生产概况及生产工艺.重点介绍了近几年钼酸铵生产工艺的技术创新,如表面活性剂的应用,蒸发设备的改进,连续结晶器的引入,循环萃取-反萃法的采用以及浸出剂的添加等,并对中国钼酸铵行业的发展提出建议.
