溶液种分过程的分解率和粒度分布
Studies showed that process and condition control had critical effect on the preparation of yig phase , and the proper conditions specialized as follows : using ammonia - ammonium nitrate ( nh3 - nh4no3 ) as precipitant , ph scope from 10 to 10 . 5 , using dissolving salt as law materials , dropping their mixed solution into precipitant , precipitation rate at 0 . 8ml / min
研究表明，共沉淀的过程和条件控制对yig的合成具有重要影响。实验得出共沉淀的合适条件为：以nh _ 3 - nh _ 4no _ 3为缓冲溶液，控制ph范围为10 . 0 ? 10 . 5 ，采用可溶性盐为原料配制溶液，滴加到沉淀剂中的共沉淀方式，共沉淀速度为0 . 8ml min左右。
