气氛烧结锶铁氧体磁粉中试实验研究

摘要

The precursor of strontium ferrite was synthesized by chemical coprecipitation method. The strontium ferrite powder was prepared by sintering the precursor at C2 atmosphere. The samples were characterized and the sintering technology including sintering temperature, sintering oxygen pressure and their interaction which have great influence on the magnetic properties of the samples were investigated. The results are very meaningful which can be a reference to the relevant counterparts.%采用化学共沉淀法合成了锶铁氧体前驱体,通过O2气氛烧结制备了锶铁氧体磁粉,并对样品进行了表征；研究了工艺技术,包括烧结温度、烧结氧气压强及两者间相互作用对磁粉磁性能的影响；得出了比较有意义的研究结果,对相关同行有一定的参考价值.
