Problems solved by technology

[0003] However, as one of the important parts of the synthesis cavity, the heating tube (made of iron-chromium-aluminum alloy band), if it is processed into a square heating tube with a square cross section, there are disadvantages such as poor repeatability in size and accuracy, and easy deformation during transportation and installation. Large-scale production, in view of this situation, the present invention proposes a new synthetic cavity assembly method, relying on the constraints of the square hole in the middle of the pyrophyllite block, or relying on the square assembly composed of square insulating tubes, square iron cups, and square graphite core columns The constraints of the assembly can solve this problem by assembling the circular tubular heating tube into a square heating tube with the internal straightener or the external straightener

Abstract

The invention relates to the technical field of diamond synthesis. The objective of the invention is to provide an assembly method of an artificial diamond square synthesis chamber that is high in dimension and precision stability and is converted from a circular tubular heating tube. The assembly method includes: (1) assembling pyrophyllite blocks; (2) subjecting the heating tube to internal correction or external correction; and (3) assembling the heating tube into the artificial diamond square synthesis chamber under conditions of internal constraints or external constraints. The artificial diamond square synthesis chamber with good dimension stability and precision stability can be obtained by correcting and assembling the original circular tubular heating tube by utilization of the method. On the premise of satisfying large-scale production, the assembling of the square heating tube is largely simplified and the method has good economic applicability.

Description

technical field [0001] The invention relates to the technical field of diamond synthesis, in particular to an assembly method of a synthetic diamond square synthesis cavity. Background technique [0002] At present, in the process of large-scale synthetic diamond synthesis, the synthetic cavity for producing synthetic diamond is mainly in the shape of a cylinder, and some parts of the synthetic cavity, such as heating tubes, heat-insulating tubes, and stems, are in the shape of round tubes or cylinders. Such shapes vary. The dimensional accuracy of the parts has good repeatability, which is conducive to the rapid assembly of the synthesis chamber. However, in today's advocacy of reducing emissions, it is of great significance to make full use of the volume of the pyrophyllite block and assemble a synthesis chamber with a larger volume. Studies have shown that making the synthesis chamber into a regular hexahedron The shape of the synthetic cavity can increase the volume of t...
