用铁砂生产锶铁氧体几个问题的研究

Investigation of Problems for Hard Sr-ferrites Magnet Produced with Iron-Sand instead of Fe_2O_3 or Iron-Scale

本文介绍用铁砂代替Fe_2O_3制备Y_(30)—Y_(35)磁性优良的锶铁氧体,铁砂的处理、配比、添加剂以及预烧工艺对磁性能的影响进行了研究.

This paper deals with Y_(30)—Y_(30) excelent hard Sr-ferrites produced with iron-Sand instead of Fe_2O_3 or iron-scale. The effects of difierent porportions, various addition and sintering techniqnes on magnetic properties have been studied.
