摘　　要：采用“过程络合法”制备了高松装密度的 Co(OH) 2 ,同时研究了影响 Co(OH) 2性能的因素。实验证明络合剂的加入是关健因素。同时反应温度、沉淀剂浓度、加料速度及方式也是重要因素。 Co(OH) 2Some cobalt hydroxide material with higher density was prepared through the process-coordination method.The main factors which affected the performance of cobalt hydroxide were studied.By the experimention,it was showed that coordination was the key factor.the reaction tmperature、precipilation concentration and the time for adding were important factors.performance of Co(OH) 2 affect performance of Co.
