Z-type ferrite composite material as well as preparation method and application thereof
The invention relates to a Z-type ferrite composite material as well as a preparation method and application thereof, wherein the preparation method comprises the following steps: (1) mixing a metal element source, a solvent and a complexing agent which form Z-type ferrite to obtain a mixed solution; (2) mixing a pH regulator with the mixed solution obtained in the step (1), regulating the pH value, and carrying out drying treatment to obtain dry gel; (3) carrying out ball milling and mixing on fused salt and the dry gel obtained in the step (2), and then sequentially carrying out vacuum plastic packaging, isostatic pressing and heat treatment to obtain ferrite powder; (4) mixing ethanol, TEOS and the ferrite powder obtained in the step (3), and carrying out heat treatment to obtain the Z-type ferrite composite material. According to the preparation method disclosed by the invention, a sol-gel method and a molten salt method are combined, so that the prepared Z-type ferrite composite material powder is good in dispersity, can effectively control the structure of crystal grains, has excellent magnetic conductivity and dielectric property, is low in production cost and simple in process, and has a relatively good industrial application prospect.
本发明涉及一种Z型铁氧体复合材料及其制备方法与应用，所述制备方法包括：(1)将组成Z型铁氧体的金属元素源、溶剂和络合剂混合，得到混合溶液；(2)将pH调节剂和步骤(1)所述混合溶液混合，调节pH，进行干燥处理，得到干凝胶；(3)将熔盐和步骤(2)所述干凝胶球磨混合后依次进行真空塑封、等静压以及热处理，得到铁氧体粉；(4)将乙醇、TEOS和步骤(3)所述铁氧体粉混合，进行热处理，得到所述Z型铁氧体复合材料。本发明所述制备方法采用溶胶凝胶法与熔盐法结合的方式，制备得到的Z型铁氧体复合材料粉体分散性好且能有效控制晶粒的结构，具有优良磁导率和介电性能，生产成本低、工艺简单，具有较好的工业应用前景。
