1概述电子级高纯高活性碳酸锰和四氧化三锰是软磁铁氧体生产的基本原料，随着我国电子工业迅速发展，对碳酸锰的需求日益增加，而且在质量上提出了愈来愈高的要求。目前我国主要仍以碳酸锰作为锰锋软磁铁氧体的原料，由于它锰含量低，烧失量大，生产过程不易控制，影响了产品质 1 Overview Electronic grade high purity and high activity of manganese carbonate and manganese oxide is the basic raw material for the production of soft ferrite, with the rapid development of China’s electronics industry, increasing demand for manganese carbonate, but also put forward more and more quality High demand. At present, manganese carbonate is still the main raw material for MnF soft ferrite in our country. Due to its low manganese content and large loss on ignition, the production process is not easy to control and affects the quality of products
