摘要
探讨了以高纯度Fe2O3、SrCO3作原料,采用CaCO3、SiO2、Cr2O3、LaCo等作 添加物,通过控制成分的摩尔比、添加物的加入量、细磨粒度等工艺技术条件,获得 高内禀矫顽力锶铁氧体的方法.
This paper discusses the methods of obtaining Sr-ferrite oxysome materials of high intrinsic coercivity by using high-purity Fe2O3 and SrCO3 as raw materials and CaCO3, SiO2, and LaCO as additives, and by controlling the molar ratio of the raw materials, the amount of the additives and the particle size of powder.
