Abstract

The invention is suitable for the technical field of diamond pressing cavities, and provides a diamond pressing cavity pressurizing device, which comprises a shell, an upper cover, a lower bottom, a diamond pressing cavity, piezoelectric ceramic and a piezoelectric ceramic lead hole, wherein the diamond pressing cavity and the piezoelectric ceramic are located between the upper cover and the lower bottom, the diamond pressing cavity is located above the piezoelectric ceramic, the piezoelectric ceramic lead hole is located in the side surface of the shell and supplies power to the piezoelectric ceramic lead, and dynamic control over pressurization of the diamond pressing cavity 40 is conducted by controlling the energizing current of the piezoelectric ceramic 60 so as to effectively ensure the pressurization continuity and controllability.

Description

technical field [0001] The invention belongs to the technical field of diamond pressure chambers, in particular to a diamond pressure chamber pressure device. Background technique [0002] The use of diamond pressure chamber technology to create a high-pressure environment and determine the physical and chemical properties of substances in extreme environments has been widely used in many fields including materials science and earth science. Traditional diamond pressure chambers use mechanical clamping devices (such as levers, bolts, etc.) to squeeze two diamond anvils that are facing each other, and generate pressure against the sample placed between them through their relative motion. [0003] However, this means of pressurization can usually only be adjusted by adjusting the tightness of the bolts, and after stopping at a certain "point", a static load related to the degree of tightness can be obtained. This mode of intermittent pressure application and pressure stop obs...
