Abstract

The present invention provides a pressure plate, which includes a cylinder assembly. A sealed chamber is arranged inside the cylinder assembly, and a sample chamber is arranged inside the airtight chamber. The diameter of the airtight chamber is D, and the diameter of the sample chamber is For d, 4d≥D≥3d. The invention also proposes a high-temperature and high-pressure synthesis equipment, including the above-mentioned pressure plate, which can ensure a more suitable volume ratio between the sample chamber and the closed cavity, thereby improving the uniformity and stability of the temperature field and pressure field during the experiment, and maintaining the stability of the device. Long-term precise control of the temperature and pressure of the sample chamber.

Description

technical field [0001] The invention relates to the field of geological experiment devices, in particular to a pressure plate and high-temperature and high-pressure synthesis equipment. Background technique [0002] The high-temperature and high-pressure synthetic press is a high-temperature and high-pressure instrument widely used in the field of international static high-pressure large-cavity experiments. By simulating the conditions of temperature, pressure, composition and oxygen fugacity inside the earth, simulate the environment inside the earth, prepare new materials, and explore the unique physical properties under high pressure. [0003] The volume ratio between the sample chamber and the closed chamber of the high-temperature and high-pressure synthetic press in the prior art is not suitable, and the volume ratio between the sample chamber and the closed chamber is too large, because there is a large gradient drop in temperature and pressure at the edge of the clos...
