The composite block is typically comprised of a perforated cube She Lashe wax block, and a heating tube, plug, and pressure transmitting material and sample inside the heating tube fitted into the bore (cavity) of the She Lashe wax block. Plugs are symmetrically arranged at two ends of a pyrophyllite block hole, and the pyrophyllite block hole has the functions of conducting electricity and transmitting pressure. After the assembly block is placed at the synthesis station of the hexahedral top press, the assembly block is pushed by the top hammer and high voltage is applied, low-voltage high current is applied at plugs at two ends after the specified pressure is reached, and a pressure transmission medium and a sample inside the heating tube are heated through the heating tube with the conductivity, so that the high-temperature high-pressure thermodynamic environment required by synthesizing the sample or the product is achieved.
The synthesis process of the hexahedral top press needs to pressurize the assembly blocks, and the assembly blocks generate plastic deformation, and is characterized in that pyrophyllite which is close to the edge of the surrounding area of the six top hammers can flow to form sealing edges due to the pressurized flow, so that the stability of the surrounding area is maintained. The closer the pyrophyllite is to the top hammer face or sealing edge area, the greater the displacement of the flow to the sealing edge area, thus causing uneven deformation of components or products inside the cavity of the assembly block.
The enlargement of the cavity of the composite assembly block is an important development trend in the composite superhard material synthesis field, and the external dimension of the conventional assembly block is generally 60mm or less. After the synthetic cavity is enlarged, the size of the assembly block is gradually enlarged, the uneven deformation of the internal components generated by the flow of pyrophyllite in the prior art is more obvious, and the phenomenon can cause the product deformation to be aggravated.
Based on the above-mentioned drawbacks of the prior art, there is a need for an improved assembly block that reduces the degree of deformation of the internal components or products.
