Problems solved by technology

However, it cannot be applied to any material system, and its target determination, composition determination, and performance testing are only applicable to heat-sensitive ferrite magnetic materials
Using combinatorial synthesis and high-throughput screening technology to develop bulk low-power ferrite magnetic materials needs to determine different targets and components, and adopt different performance testing methods, which have not been reported at home and abroad.

Abstract

The invention relates to a practical low power consumption manganese-zinc ferrite material that is compounded by low power consumption manganese-zinc ferrite material and uses the method of high pass filtering method, the target is in range of 100-500 kHz. By adjusting the proportion of Fe2O3, ZnO and Mn3O4, altering grinding time, pre-firing time, sintering temperature and sintering atmosphere, abundant manganese-zinc ferrite material would be produced. Building a sample room, testing by power consumption-temperature manganese feature testing system controlled by computer, building database of constituent-manufacture technology-manganese feature, taking second filtering of the material that basically meet target request, the precursor material would be gained. Then, large scale produce would be taken. The invention could shorten the research cycle of low power consumption manganese-zinc ferrite material. And it could quickly find the excellent material.
