Synthesis block for synthesizing artificial diamond

Abstract

The invention discloses a synthesis block for synthesizing artificial diamond. The synthesis block is positioned in a high-temperature and high-pressure six-surface propping and pressing machine, a cavity used for sheathing and accommodating a graphite block is arranged inside the synthesis block, the cavity penetrates through the two opposite sides of the synthesis block, the synthesis block is formed by combining two or more than two split blocks, heating sheets are arranged between the split blocks, the split blocks consist of a first split block ands a second split block, the cavity is in a cylindrical shape, and the heating sheet is a metal heating sheet or a graphite heating sheet and is positioned between the first split block and the second split block. The synthesis block has the beneficial technical effects that the synthesis block is formed by combining two ore more than two split blocks, the heating sheet is arranged between the split blocks, the heat can be sufficiently utilized, the heat utilization efficiency can be improved on the premise of not changing the high-temperature and high-pressure major environment, in addition, the pressure transfer, sealing, thermal isolation and insulation effects cannot be influenced, and the yield and the quality of the diamond are further improved.

Description

technical field [0001] The invention relates to a synthetic block, in particular to a synthetic block for synthetic synthetic diamond. Background technique [0002] In the prior art of artificial diamond, the graphite raw material in the synthetic block in the top press is converted into diamond through a six-sided top press under constant ultra-high temperature and high pressure conditions. The synthetic block is one of the key elements, but even if it is ensured Under the premise of high temperature and high pressure, there are still defects such as low diamond output and low thermal energy utilization efficiency, which can no longer meet people's needs. Contents of the invention [0003] The object of the present invention is to provide a synthetic block for synthetic synthetic diamond with high thermal energy utilization efficiency and high diamond yield, so as to solve the shortcomings of the prior art. [0004] The present invention adopts following technical scheme...
