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。
This paper describes the methods and conditions for the conversion of amorphous Nb 2 O 5 · nH 2 O into crystals at 120 ° C. Nb 2 O 5 · nH 2 O was dissolved in sulfuric acid and neutralized with ammonia (NH 3 · H 2 O) to a pH value of 1. The templating agent was added to the reactants and filled into a rigid glass tube, sealed and crystallized at 120 ° C. for 48 hours Form a new crystal. The X-ray diffraction study obtained a new crystal form.
