1.热处理法 以硫酸法制造二氧化钛和副产硫酸亚铁和氢氧化钠为原料，制备合成云母氧化铁。主要反应式如下。
将硫酸亚铁溶解，加入氧化剂（HNO3）将亚铁氧化为高价硫酸铁，用氢氧化钠中和，在高压釜中将亚氧化铁在高压、高温和浓碱中水热处理制得云母氧化铁结晶，过滤、洗涤、干燥即得六角片状α-Fe2O3，粒径可控制在2～60μ，径厚比为（1∶10）～（1∶30）。
2.熔融复盐高温氧化法 以金属铁、氯气和氯化钠为原料，制备合成云母氧化铁。主要反应式如下。
本方法采用的主反应器为衬有耐火材料的圆柱形钢筒，其顶部和底部配有盖子，气体从底部进入，顶部排出。
首先在反应器底部装入一层填料和耐火材料块支撑层，在其上装入一厚层铁屑、盐和耐火材料块的混合物，预热反应器中填充物料底部至约700℃，通入氯和空气混合物进行氯化和复合，氯与铁屑和盐反应，在耐火材料块支撑物表面形成一层氯化钠氯化铁复盐（如NaFeCl4），氯气加入量应控制反应区高度仅为反应物填充层总高度的几分之一。通入空气进行氧化，氧与熔融状态的NaFeCl4反应，生成被包裹在盐层中的片状氧化铁晶体，同时放出的氯气从反应区上移进而形成新的反应区，重复上述过程直至氯气从反应器顶部排出，反应即结束，从反应器底部放出填充物，溶解耐火材料块上的盐层，过滤收集合成云母氧化铁，经洗涤、干燥、分级即制得合成云母氧化铁，其厚度为0.5～5μm，直径1～100μm。控制反应条件和分级条件可获得不同粒径、不同厚度以及所需粒度分布的产品。
