摘　　要：以硫酸钴、氨水及氢氧化钠为原料,采用络合控制结晶法制备了Co(OH)_2,其结构经XRD和SEM表征。研究了反应条件对产物的影响。结果表明:氨钴质量比为0.3,pH 9~11.5时,β-Co(OH)_2的形貌较规则。Co（OH）2 was prepared by ammonia complexation control crystallization method,using cobalt sulfate,ammonia and sodium hydroxide as raw material. The structure was characterized by XRD and SEM. Effects of reaction conditions on the products were investigated. The result indicated that β-Co（OH）2 exhibited well microstructure under the conditions as followed： m（ ammonia）/m（ cobalt） =0. 3,pH 9 ~ 11. 5.
