具有纳米尺度的晶体材料。不同熔烧温度(300～700℃)，可得不同粒径(10～60nm)的铁酸锌材料。采用硫酸亚铁和硫酸锌混合，制得碱式碳酸盐前驱体，然后直接焙烧制备出铁酸锌纳米晶体材料。铁酸锌是性能优良的软磁材料、丁烯氧化脱氢的催化剂，具有很高的光催化活性及对可见光敏感的半导体催化剂。铁酸锌纳米晶体粒子是性能优良的透明无机颜料。 Zinc iron oxide nanoparticles are chemically stable and exhibit superparamagnetic properties. There are a number of methods to prepare ZnO nanoparticles, some of them are self-propagated combustion of fuels (alanine, glycine and proline), co-precipitation, sol-gel reaction, spin coating, ball milling and auto combustion.
