Embodiment Construction

[0027] The present invention will be further described below by means of the accompanying drawings and specific embodiments.

[0028] Step 1, collecting beryllium ore samples;

[0029] Collect beryllium ore samples through field geological surveys or surveys. The sample size is 2cm×5cm×8cm or 3cm×6cm×9cm; the number of samples is 1 to 3 pieces; because of the in-situ micro-area quantitative analysis, usually one beryllium mineral (that is, one sample) can meet the testing requirements. In order to prevent the impact of unforeseen factors (such as sample damage during sample preparation, diversity of beryllium mineral types, and statistical needs, etc.), it is recommended to collect two more samples.

[0030] Step 2, making a probe sheet or light sheet;

[0031] Mechanically grind and polish the beryllium ore sample collected in step 1 to make a probe sheet or light sheet. The size of the probe sheet is 2cm×2cm×1cm; the size of the light sheet is 2cm×3cm×0.3mm.

Abstract

The invention belongs to the technical field of beryllium ore analysis and testing, and particularly relates to a method for in-situ micro-area quantitative analysis of beryllium content, and the method comprises the following steps of: collecting a beryllium ore sample; manufacturing the beryllium ore sample into a probe sheet or a polished thin sheet; identifying beryllium minerals, and thermally evaporating a carbon film on the surface of the probe sheet or polished thin sheet sample; and performing in-situ micro-area quantitative analysis on beryllium minerals. By arranging a light splitting crystal directed at large-size interplanar spacing of ultra-light elements and arranging a pulse height analyzer, in-situ micro-area quantitative analysis of beryllium minerals can be achieved, micron-level nondestructive analysis can be conducted on the beryllium minerals, component information of the beryllium minerals in the micro-area scale can be obtained easily, and by means of the testing method and technology, the method has no complex sample preparation process, and has the advantages of in-situ, micro-area, lossless, real-time, simple and convenient operation, high sensitivity and the like.

Description

technical field [0001] The invention belongs to the technical field of beryllium ore analysis and testing, and in particular relates to a method for in-situ micro-area quantitative analysis of beryllium content. Background technique [0002] Beryllium is the lightest alkaline earth element. Metal beryllium and its series products are indispensable functional materials in high-tech fields such as atomic energy, national defense industry, aerospace, metallurgical industry, automotive electronic equipment, high-end electrical appliances, telecommunications infrastructure, computers, new energy vehicles, medical treatment, and oil and gas exploration. Structural materials and key raw materials, thus known as "space metal", "cutting-edge metal", "super metal", "nuclear reactor protector". Since beryllium cannot be replaced by other materials, beryllium plays an extremely important role in the systematic construction and strategic development of the core capabilities of national ...
