【摘要】 探讨了反应温度、通气量、搅拌转速、初始混合状态等对晶种制备过程氧化速率及晶种形态的影响。发现晶种制备阶段存在溶解。氧化动态平衡过程，此时溶液ｐＨ值和［Ｆｅ￣（２＋）］基本不变；在２５～５０℃范围内可制得形态较好的单一相α－ＦｅＯＯＨ；随通气量和搅拌转达增加，晶种位子粒度分布趋于均匀，枝叉和孪晶减少；初始混合状态对品种最终形态影响不大。更多还原

【Abstract】 Based on the study of the reaction process of seed formation,the effects of temper-ature,air flow rate,stirring speed,initial mixing condition on the reaction rate and the seed formwere studied systematically. The results revealed that the dissolution-oxidation dynarnic equilibri- um existed in the seed formation process,pH and [Fe￣(2+)] changed little with chemical reaction.The width of paticle size distribution,dendrite and twin crystal decreased with increasing air flowrate and stirring speed,and the optimum temperature was 25～50℃.更多还原
