摘　　要：介绍了在生产永磁铁氧体过程中,添加剂含量对料浆粒度、产品收缩率的影响,实验表明,在其他实验条件相同的情况下,随着复合添加剂含量的增加,料浆粒度逐渐减小;随着添加剂含量的增加,铁氧体产品的轴向收缩率逐渐增大,而径向收缩率先逐渐减小后趋于稳定。The effect of additive content on particle size and shrinkage rate was introduced in the process of producing permanent ferrite.The experiment shows that with the increase of the content of compound additives,the particle size of slurry is gradually reduced under the same condition of other experimental conditions.Along with the increase of the content of the additive,the axial shrinkage rate increases gradually,and the radial shrinkage decreases and then tends to be stable.
