The molybdic acid aggregates with diameter of 1--2μm and length of several decades-micron can be obtained by the reaction of higher-concentration ammonium molybdate with HNO3 in a coexisting HAc or CTAB solution, repectively.

较高浓度的钼酸铵分别在醋酸和CTAB调节下与硝酸反应均可制备直径为1~2μm，长为数十微米的细长晶须，经过500~600℃烧结后则相应变为纳米级片状和颗粒状α-MoO3粉体；低浓度的钼酸铵在CTAB调节下与盐酸反应可制备不规则的晶体棒，经过烧结后得到颗粒状α-MoO3粉体。

Molybdic acid aggregates were prepared by the reaction of ammonium molybdate with HNO_3 and HCl in a coexisting HAc or cetyl-trimethyl ammonium bromide solution,respec- tively.

钼酸铵[分子式为(NH4)2Mo4O13·2H2O或(NH4)6Mo7O24·4H2O]是石油化学工业和高分子合成工业催化剂、陶瓷彩釉和颜料、特殊分析试剂和药物以及生产金属钼丝、片等的重要原料[1]，工业上通常采用将精钼砂焙烧、硝酸浸洗、氨水浸出、净化和加酸沉淀等一系列工艺流程。

The results showed that monocarboxylic acid stearic acid played a role of surfactant, and the product was still orthorhombic Ce2O(CO3)2·H2O with a high crystallization degree. In turn, duality-carboxylic acid tartaric acid...

实验结果表明在尿素及硝酸铈的混合溶液中分别加入一元羧酸硬脂酸，二元羧酸酒石酸和三元羧酸柠檬酸时，一元羧酸硬脂酸在混合溶液中只起表面活性剂的作用，其产物为斜方晶系的单晶Ce2O(CO3)2.H2O微粉，且表面活性剂硬脂酸的加入使得晶体的晶化程度明显提高；而二元羧酸酒石酸与三元羧酸柠檬酸在均相反应中则起螯合剂的作用，分别与Ce3+形成螯合物酒石酸铈和柠檬酸铈，这些结果的造成是由于其反应机理的不同所导致的。
