Baseing on the request of low coercivity and high squareness in application , we had confirmed the main formulation of the lizn ferrite ; during the study of the conventional ceramic process , with the main formula foundation , we mainly studied the influence of ti4 + , co3 + on lowering coercivity and bi2o3 , v2o5 on lowering sinter temperature . the results showed bi2o3 good characteristic on lowering sinter temperature and the sample which mixed with 1 % bi2o3 could reduce 40 % coercivity through slowing heating rate and extending the holding time 在氧化物陶瓷工艺技术研究中,按实际应用中低矫顽力、高矩形比的要求,确定了lizn铁氧体的主配方,在主配方基础上进行了ti4 + 、 co3 +等离子对降低矫顽力的研究以及添加bi2o3 、 v2o5助熔剂对降低烧结温度的研究,发现bi2o3具有优良的降低烧结温度的特性,在添加bi2o3样品烧结过程中,降低升温速率,延长保温时间可以降低40 %左右的矫顽力。
