Description

Technical Field

[0001] The utility model relates to the technical field of artificial diamond related equipment, in particular to a butterfly-shaped cavity. Background Art

[0002] The manufacturing process of artificial diamonds is mainly carried out in a laboratory environment, using advanced technology to simulate the conditions under which diamonds grow naturally in the mantle. This includes using methods such as chemical vapor deposition (CVD) or high temperature and high pressure (HPHT) under extreme pressure and temperature to arrange carbon atoms into a diamond crystal structure. Specifically, these methods include using graphite or diamond powder as a carbon source, and in a high temperature and ultra-high pressure reaction chamber, through the action of a metal catalyst, carbon atoms are deposited on a diamond seed crystal to form gem-quality diamonds. The cavity for artificial diamond manufacturing has a butterfly cavity, and the CVD butterfly cavity can be used to manufacture artificial diamonds.

[0003] The butterfly cavity of the prior art needs to maintain good sealing when in use. However, due to process problems during manufacturing, some butterfly cavities may have sand holes in the cavity of the butterfly cavity. When the butterfly cavity is in a high temperature and ultra-high pressure environment for a long time, these sand holes are likely to cause deformation of the butterfly cavity, thereby causing some hidden cavity sand holes to be exposed, resulting in the cavity of the butterfly cavity being unable to ensure sealing. For this reason, we propose a butterfly cavity. Utility Model Content
