Preparation method of microwave ferrite
The invention discloses a preparation method of microwave ferrite, and belongs to the technical field of ferrites. The preparation method comprises the steps of (A) molding powder to obtain a green body; (B) sintering the green body to obtain a half-clinkered blank; (C) processing the half-clinkered blank to obtain a semi-finished product; and (D) sintering the semi-finished product to obtain a ferrite matrix finished product. According to the invention, through step-by-step sintering and grinding processing of the half-clinkered blank between two steps of sintering, the problem that a substrate with a special structure required by a novel microwave ferrite device is difficult to produce and process is solved. Compared with an existing one-step sintering method, the method has the advantages that direct and complex processing of a polycrystalline clinkered blank with high hardness and brittleness is avoided, large-scale production capacity is achieved, the yield is increased by reducing processing stress damage, the processing difficulty of the special-shaped ferrite substrate is greatly reduced, and low-cost and batch production of the microwave device with the special-shaped structure substrate is facilitated.
本发明公开了一种微波铁氧体的制备方法，属于铁氧体技术领域，步骤（A）将粉料成型得到生坯；（B）将生坯进行烧结得到半熟坯；（C）将半熟坯加工得到半成品；（D）将半成品进行烧结得到铁氧体基体成品；本发明通过分步烧结并在两步烧结之间对半熟坯进行磨削加工，从而解决新型微波铁氧体器件所需的具有特殊结构的基片难以生产加工的问题；相比于现有的一步式烧结法，本发明避免了直接复杂加工具有高硬度与脆性的多晶熟坯，具备大批量生产能力，通过降低加工应力破坏从而提高良品率，极大地降低了异形铁氧体基片的加工难度，有利于异形结构基片的微波器件的低成本、批量化生产。
