Technical Field

[0001] The utility model belongs to the technical field of diamond heating, and in particular relates to a single crystal low-strength diamond indirect heating device. Background Art

[0002] At present, the heating technology in diamond synthesis is gradually replaced by indirect heating due to the many shortcomings of direct heating. Indirect heating usually adopts the method of setting a heating element in a high-pressure cavity for heating. The core column and the heating element are separated by insulating materials, or electric heating is adopted in a metal pipe, so that the heat is transferred to the synthesis rod through the insulating layer coated on the heating tube. The synthesis rod synthesizes diamond under high temperature and high pressure. These indirect heating structures are found to have many shortcomings in use: low heating efficiency, uneven heating, and the metal heating plate is prone to ablation at high temperature, resulting in frequent alarms, affecting the stability of diamond synthesis, production efficiency and product quality; and harmful impurities in the air are easy to enter the diamond, affecting the quality of the diamond.
