仲钨酸铵是生产金属钨粉的重要中间产品。目前高纯钨粉的生产,几乎无例外地是以APT为初始原料。国外研究认为,还原钨粉的粒形和粒度与APT原料的结晶形态密切有关。APT晶体的粒度和形貌,将直接影响到后续还原阶段的控制。随着现代科学技术的飞跃发展,世界各国对各种粒度和不同粒形钨粉的生产,提出了越来越多的要求。
Ammonium paratungstate is an important intermediate product for the production of tungsten metal powder. At present, the production of high-purity tungsten powder is almost without exception APT as the initial raw material. Foreign studies believe that reducing the size and particle size of tungsten powder and APT raw materials closely related to the crystalline form. APT crystal size and morphology, will directly affect the control of the subsequent reduction phase. With the rapid development of modern science and technology, various countries in the world have put forth more and more requirements on the production of various granular and different granular tungsten powders.
