Abstract

A process for synthesizing and high throughput screening the thermosensitive Mn-Zn ferrite series with -40 - +160 deg.C of temp range, more than 2000 of magnetic conductivity and excellent characteristics includes creating specimen materials library for different formulas and technologies, computer controlled characteristics analysis to obtain library characterization, creating specimen components-preparing process-physical property database, classifying, choosing raw materials, optimizing, screening pilot materials, and experimental preparing. Its advantages are high efficiency and low cost.

Description

Technical field: [0001] The invention relates to a combined synthesis and high-throughput screening method for heat-sensitive manganese-zinc ferrite series materials, that is, a method for efficiently developing heat-sensitive MnZn ferrite series materials by using combined synthesis and high-throughput screening technologies. Background technique: [0002] Combinatorial synthesis and high-throughput screening technology originated from the combinatorial chemistry technology proposed by H.Geysen et al. in the 1980s. Subsequently, in the process of developing new drugs, combinatorial chemistry and high-throughput synthesis and screening technologies were further developed, which greatly accelerated the development process of new drugs. In the field of new drug discovery, annual screening of 1 million different compounds was achieved in 1999, and the R&D cost of each lead drug was reduced by about two orders of magnitude. [0003] In 1995, Dr. Xiang Xiaodong and Professor P.G...
