Phase content calculation method and system based on energy spectrometer component detection data

Abstract

The invention discloses a phase content calculation method and system based on energy spectrometer component detection data. The phase content calculation method includes the steps that the detectioncontent of m elements in a sample to be detected is obtained; the detection content of the a element is Ta, wherein a is greater than or equal to 1 and less than or equal to m; n phases containedin the sample to be detected are obtained; the n phase contents are used as a calculation variable to establish an optimization problem, and the goal of the optimization problem is to minimize the error between the detected content of the detected elements and the calculated content; and the optimal solution of the optimization problem is the content of the n phases containing all detection elements. The phase content calculation method can accurately calculate the phase content by analyzing the element data through an energy spectrometer; and the phase contained in a damaged refractory material can be quantitatively analyzed.

Description

technical field [0001] The invention relates to the field of metallurgical technology detection, in particular to a method and system for calculating phase content based on component detection data of an energy spectrometer. Background technique [0002] Energy Dispersive Spectrometer (Energy Dispersive Spectrometer) is used to analyze the types and contents of elements in micro-regions of materials, and is used in conjunction with scanning electron microscopy and transmission electron microscopy. The basic detection principle is: each element has its own X-ray characteristic wavelength, and the size of the characteristic wavelength depends on the characteristic energy △E released during the energy level transition process. The energy spectrometer uses the different characteristic energy of X-ray photons of different elements. This feature was used for component analysis. In the specific operation process, after the X-ray characteristic signal is received by the probe, it i...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing energy spectrometer analysis process can only obtain the percentage content of each element, but the current XRD phase quantitative detection technology is still inaccurate, and it strongly relies on the phase information in the PDF database. The incomplete information of complex mineral data limits the quantification of phase composition
