Diamond anvil cell device

Abstract

The invention relates to high-voltage experimental equipment, and provides a diamond anvil cell device which comprises a press cylinder upper die and a press piston lower die. A plurality of upper supporting wings are arranged on the side wall of the press cylinder upper die, upper pressing screw holes are formed in the upper supporting wings in an axially penetrating manner, lower supporting wings in one-to-one correspondence to the upper supporting wings are arranged on the side wall of the press piston lower die, lower pressing screw holes in one-to-one correspondence to the upper pressingscrew holes are formed in the lower supporting wings in an axially penetrating manner, first tapered holes are formed in the press cylinder upper die and the press piston lower die in an axially penetrating manner, a diamond anvil cell is embedded into the top of each first tapered hole, two opposite upper half tapered holes are formed in the side wall of the press cylinder upper die, lower half tapered holes in one-to-one correspondence to the upper half tapered holes are formed in the side wall of the press piston lower die, and each upper half tapered hole and the corresponding lower half tapered hole enclose a second tapered hole leading to the corresponding diamond anvil cell. The diamond anvil cell device is small in size and light in weight, and axial and radial working distances can be remarkably shortened.

Description

technical field [0001] The invention relates to high-pressure experimental equipment, in particular to a diamond counter-anvil device. Background technique [0002] In the field of high-pressure experimental science, static high-pressure experiments are mainly used to study the changes in the structure and properties of substances caused by pressure under quasi-hydrostatic conditions. Static high pressure technology is a technology that slowly applies a load to the processed object through external mechanical loading, so that a high pressure is generated inside and can be maintained for a long time. [0003] Diamond anvils are currently the only devices capable of compressing submillimeter-sized materials to static pressures in excess of million atmospheres. Diamond anvils are widely used in geosciences, condensed matter physics, chemistry, and materials science. For example, by combining diamond anvils with a heating system, high temperature and high pressure conditions ca...
