Abstract

The invention discloses a method for implementing rapid measurement on contents of elements of lanthanum, calcium and cobalt in a high-performance magnetic material BMS-12. An X-ray fluorescence spectrometer is used as a detection instrument, and working parameters of the spectrometer are determined in advance; a standard sample wafer of the high-performance magnetic material BMS-12, which is pressed in advance by utilizing a powder pressing method, is combined with a chemical measuring mode to determine the working parameters of the X-ray fluorescence spectrometer. The method comprises the following steps of: S1, establishing a standard curve; S2, measuring the actual measurement sample wafer, and when subsequently measuring other actual measurement sample wafer, repeating the measurementprocess of step S2. According to the method, the current situation of complex and unstable chemical analysis process is changed, the analysis level and analysis quality are improved, a great amount of human and material resources can be saved for a laboratory, and indirect economic benefits are generated.

Description

technical field [0001] The invention relates to a method for determining the element content of magnetic materials, in particular to a method for realizing the rapid determination of the content of lanthanum, calcium and cobalt in the high-performance magnetic material BMS-12. Background technique [0002] Permanent magnet ferrite material is an important functional material, which is widely used in various electric power and electronic products. BMS-12 is a high-performance La-Ca-Co permanent magnet ferrite material newly developed by Beikuang Magnetic Materials Co., Ltd. Its main components are iron, strontium, lanthanum, calcium, cobalt, etc., but currently the laboratory has The technical conditions can only quantitatively analyze the content of iron, strontium, calcium and other elements in it, and its pre-treatment process is complicated, the detection process is cumbersome, and it is impossible to quickly detect the BMS-12 production samples. In particular, elements ...

AI Technical Summary

Problems solved by technology

Cobalt is measured using the iodometric method (see figure 1 ) and atomic absorption spectrometry, using iodometric method and atomic absorption spectrometry to measure the content of cobalt element, all need cobalt element to be measured in the form of solution, and BMS-12 product is solid powder, so use iodometric method and atomic absorption spectrometry The detection process of the method is complicated, and it is impossible to quickly and efficiently measure the content of Co in BMS-12

At present, there is no unified standard method for the detection of lanthanum. Low content lanthanum can be used by inductively coupled plasma atomic emission spectrometry (ICP-AES), but there is no unified national standard measurement method for lanthanum with a high content.

[0005] In summary, the current existing methods for determining the content of lanthanum and cobalt elements cannot quickly determine the content of lanthanum, cobalt and other elements in the new high-performance magnetic material BMS-12, and there is no rapid analysis of ferrite Related reports on the content of elements such as lanthanum and cobalt in magnetic materials
