摘 要: | 本文叙述在120℃下使无定型Nb_2O_5·nH_2O转化为晶体的方法和条件。Nb_2O_5·nH_2O溶解于硫酸里,用氨水(NH_3·H_2O)中和至PH值为1,把模板剂加入反应物中,并装入硬质玻璃管内,封口,在120℃下晶化48小时可形成新的晶体。经X射线衍射研究得到的是新晶型。

Abstract: | The condition and method that amorsphous body Nb_2O_5·nH_2o is Transformed into a crystal at 120℃ are given. Nb_2O_5·nH_2o dissolves in the sulphuric acid. We use amonia water to neutralize it up to pH=1, and add a crystallizing agent. The mixture is fell into a hardness glass tube, and seal the glass tube.When the mixture is crystallized for fourty eight hours at 120℃, the crystal formations are obtained.An X—ray diffraction study shows that the crystal is a new structure. |
