Description

Technical Field

[0001] The present invention relates to the technical field of synthetic technology of artificial crystals, and particularly relates to a synthetic device for life diamonds. Background Art

[0002] Carbon elements extracted from biological samples such as biological hair and bone ash are used. The HPHT method is used for diamond synthesis, which is a relatively mainstream life diamond synthesis technology nowadays.

[0003] The HPHT technology uses a six-sided press to place graphite and a second metal catalyst in a diamond cultivation chamber made of pyrophyllite. Under an artificial high-temperature and high-pressure environment, the graphite undergoes a phase transformation to form diamonds. With the participation of the second metal catalyst (such as Fe, Ni, Co, Mn, etc. and their alloys), the conditions required for the phase transformation of graphite into diamonds will be significantly reduced compared to the natural environment. Usually, the pressure is 5.4 GPa and the temperature is 1400 °C.

[0004] The existing pyrophyllite diamond cultivation chamber is a long cylinder with a round inner and square outer shape. Electrodes, graphite, and a second metal catalyst need to be placed in the internal cylindrical empty chamber. In the existing production method, multiple seed crystals are placed in the growth chamber at the beginning of cultivation, and multiple diamonds can be synthesized simultaneously within one cultivation cycle. However, it is impossible to distinguish the source of carbon elements of each diamond during its formation process. It is precisely under such conditions that currently, only one seed crystal can be placed in each diamond growth chamber during the synthesis process of life diamonds. Therefore, the production efficiency is much lower than that of ordinary cultivated diamonds, resulting in a high manufacturing cost of life diamonds. Summary of the Invention

[0031] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.

The heating assemblies 16 at both ends can be controlled separately and are mainly composed of a heating sheet 6 and a heating electrode 5. The synthetic assembly 17 includes carbon elements that can be converted into diamonds. Since there are independent synthetic assemblies 17 and heating assemblies 16 in each growth chamber 3, the carbon elements in each growth chamber 3 can undergo a phase change in an independent space and be converted from graphite to diamonds, completely eliminating the possibility of carbon element confusion, ensuring the purity of the source of the second carbon source 10 of life diamonds, improving production efficiency, and greatly reducing production costs. Moreover, by controlling the heating temperature of the heating assembly 16 in different growth chambers 3, the heating temperature of the carbon elements in different growth chambers 3 can be controlled separately.
