摘　　要：以硫酸法钛白粉工艺副产硫酸亚铁为原料,净化除杂后,再加入硫铁矿和碱式碳酸镁,高温煅烧耦合制备铁酸镁,可解决钛白粉副产硫酸亚铁的堆积问题,并且生成价值更高的铁酸盐,变废为宝。利用X射线衍射分析、红外光谱、比表面积和扫描电镜等研究了固相产物的物相结构、粒径尺寸和表面形貌。结果表明,该合成方法可成功制备尖晶石型纳米级铁酸镁。After purification, the titanium dioxide by-product ferrous sulfate can be utilized to prepare high value magnesium ferrite through high-temperature calcination reaction by adding pyrite and basic magnesium carbonate. This way can solve the accumulation problems of titanium dioxide by-product X-ray diffraction （XRD）, fourier transform infrared spectrum （FTIR）, brunauer-emmett-teller （BET） method and scanning electron microscopy （SEM） are used to study the phase structure, particle size and surface morphology of the solid-phase products. The results show that the spinel nano-sized magnesium ferrite can be successfully prepared by this synthesis method.
