Preparation method of Z-type hexagonal ferrite material
The invention provides a preparation method of a Z-type hexagonal ferrite material, which comprises the following steps: mixing barium source and iron source raw materials to obtain a first mixture; mixing a barium source, an iron source and a substituted metal source raw material to obtain a second mixture; independently and sequentially carrying out presintering, granulation molding and sintering on the obtained first mixture and second mixture to respectively obtain an M-type ferrite precursor and a Y-type ferrite precursor; and mixing the obtained M-type ferrite precursor with the Y-type ferrite precursor, and sequentially carrying out granulation molding, sintering and annealing to obtain the Z-type hexagonal ferrite material. According to the preparation method, a mixed calcination method is adopted, so that the prepared Z-type hexagonal ferrite material basically has no impure phase. The method is simple to operate and relatively low in cost, and has a relatively good industrial application prospect.
本发明提供了一种Z型六角铁氧体材料的制备方法，所述制备方法包括：将钡源与铁源原料混合，得到第一混料；将钡源、铁源和取代金属源原料混合，得到第二混料；将得到的第一混料和第二混料独立地依次进行预烧、造粒成型以及烧结，分别得到M型铁氧体前驱体和Y型铁氧体前驱体；将得到的M型铁氧体前驱体和Y型铁氧体前驱体混合后依次进行造粒成型、烧结以及退火，得到Z型六角铁氧体材料。本发明所述制备方法采用混合煅烧法，制备得到的Z型六角铁氧体材料基本不存在杂相，操作简单，成本较低，具有较好的工业应用前景。
