The invention discloses a ferrite formula correction process and ferrite. The ferrite formula correction process comprises the following steps: determining a formula needing to be corrected and a corresponding share of the formula; the corrected formula is subjected to presintering; correcting the pre-sintered and corrected formula according to the corresponding share of the pre-sintered and corrected formula; when the formula of the ferrite is corrected, the to-be-corrected formula is pre-sintered, and then the pre-sintered to-be-corrected formula is corrected according to the corresponding share, by adopting the formula correction process, due to the fact that the correction raw materials are pre-sintered and are the same as the ferrite matrix powder, the correction accuracy and the correction proportion are easier to control, and the correction proportion can reach 30wt%; and the physical characteristics of the granules are not influenced, the consistency is better, the shrinkage consistency of the magnetic core can be obviously improved, the activity change of the corrected powder is small, and the abnormal growth phenomenon of crystal grains and the occurrence of crystal spots can be effectively reduced in the sintering process, so that the comprehensive performance of ferrite can be improved.
本发明公开一种铁氧体的配方补正工艺及铁氧体，包括步骤：确定需要进行补正的配方及其对应的份额；将所述补正的配方进行预烧；将预烧后的所述补正的配方按照其对应的份额进行补正；在进行铁氧体的配方补正时，先将待补正的配方进行预烧，再将预烧后的待补正的配方按照其对应的份额进行补正，采用上述配方补正工艺，由于补正原料经过预烧，与铁氧体基体粉料相同，补正的准确率和比例更容易控制，补正比例可达30wt％，并且颗粒料的物理特性不受影响，一致性较好，可明显提高磁芯收缩的一致性，同时补正后粉料的活性变化小，在烧结过程中可有效的降低晶粒异常生长现象与晶斑的出现，从而能够改善铁氧体的综合性能。
