Heat-sensitive Mn-Zn ferrite series material combined synthesis and high throughput screening method

Abstract

A combinatorial synthesis and high-throughput screening method for thermosensitive manganese zinc ferrite series materials, the target is a practical thermosensitive material with a magnetic permeability μ > 2000 and excellent μ-T characteristics within the temperature range of -40°-+160°C Manganese zinc ferrite series magnetic materials, through different material formulas and preparation processes, establish a sample material library, use a computer-controlled μ-T characteristic test system to analyze and obtain library characterization, and establish a database of sample composition-preparation process-physical properties , After collecting and sorting, conduct primary selection of materials, conduct further analysis and research and optimize, screen out leading materials, and then carry out large-scale trial production. The high-throughput combination design, preparation and screening method of the present invention not only has high efficiency and low cost, but also can greatly shorten the cycle of developing new materials, and is especially suitable for preparing multi-component complex mixtures and serial compounds, so as to obtain a large number of new materials Or materials with excellent performance.

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...
