摘要
发现形成d值为6.249、3.637、3.545、3.122、2.740、2.333、2.086、2.060主要衍射线的α-NiWO_4新结晶相。它的晶粒度较小,热稳定性较好,是X射线衍射卡中已知NiWO_4结晶相的前身物。文中介绍了它的制备方法、物化性质和对催化活性的影响。
A new crystal phase α-NiWO_4 has been found with main diffraction lines being 6.249, 3.637, 3.545, 3.122, 2.740, 2.333, 2.086, 2.060(d value). Its crystal size is small and thermal stability is good. It is the precursor of the well known NiWO_4 crystal phase. The preparation method, physico-chemical properties of this compound and its effect on catalyst activity are presented.
