Problems solved by technology

However, one of the biggest problems existing in the current equipment and devices is that they cannot provide spectroscopic characterization means, which brings some confusion to researchers in the study of the state of matter structure under supercritical reaction conditions: To study the structure of matter under high-pressure conditions, one can only infer a structural change characteristic of the material itself through the study of the material after un

Abstract

The invention discloses a supercritical in-situ spectrum reaction device which comprises a gas path system, a heating system, a water cooling system, a sample cover and a light supply device. The heating system is wrapped with a water cooling system for cooling the heating system; the interior of the heating system is connected with the gas output end of the gas path system, and the gas path system provides required test pressure for the heating system through gas pressure intensity; the light supply device penetrates through a heating area of the heating system; the sample cover is fixed at the front end of the light supply device for providing different spectral light sources; and a sample cavity for placing a sample is formed in the central position of the sample cover. According to the invention, the light supply device controls the light so as to reduce the influence of an external light source on the test and the test accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of material structure-mechanism in-situ characterization, in particular to a supercritical in-situ spectral reaction device. Background technique [0002] Structural studies of disordered states of matter under conditions of extreme pressure and temperature are an attractive field of science. The reason lies in the importance of characterizing the dependence of the structure of matter on temperature and pressure to gain insight into key bonding interactions. One of the most typical is the solubility of metal ions in solution. As has been reported, the in-depth analysis of the solubility and morphology of Cu ions in aqueous fluids in different pH ranges, different temperature and pressure ranges. Hemley et al. measured the solubility of Cu in 1 molar chloride solution under different conditions of temperature ranging from 300 to 500 °C and pressures of 50, 100 and 200 MPa, and found that it decreased slight...
