摘　　要：高浓度Ｆｅ３＋盐溶液的催化相转化制备均匀铁红胶粒魏雨（河北师范大学化学系，石家庄０５００１６）赵建路韩秀玉（石家庄教育学院，石家庄０５００３１）关键词三氧化二铁，铁红，均匀胶粒，催化相转化分类号Ｏ６４３／Ｏ６１４金属盐溶液高温水解相转化是制备均匀氧...Uniform submicrometer (0 3 μm) hematite particles were prepared in the presence of Fe 2+ ions by forced hydrolysis of boiling reflux from high concentrated FeCl 3 solution of 1 0 mol/L, c (Fe 3+ )/ c (Fe 2+ )=50～80, pH=4 5～5 0 for 10 h. When NaH 2PO 4 solution had been added, the pseudocubic particles turned into spindle shape hematite particles. A catalytic phase transformation of Fe(OH) 3 gel by Fe 2+ is interpreted in terms of an electron transfer redox process.
