Description

[0001] technical field [0002] The invention belongs to the field of electric heating automatic control, and relates to a synthesis device and a synthesis method for precisely controlling the synthesis temperature of industrial diamonds. Background technique [0003] In the synthesis process of industrial diamonds, industrial diamonds are grown under certain pressure and temperature conditions. The pressure generates high pressure by extruding the synthetic block, and the temperature generates high temperature by electrifying the carbon tubes in the synthetic cavity in the synthetic block. In the process of industrial production, the synthesis quality of industrial diamonds is mainly controlled by controlling the synthesis pressure and the temperature of the synthesis chamber. Due to the fluctuation of raw materials and changes in the surrounding environment during the industrial production process, the synthesis pressure and the temperature inside the synthesis chamber are...

Problems solved by technology

However, because the temperature inside the synthesis chamber is as high as 1300~1500 degrees, it can only be measured by platinum-rhodium alloy resistance wire, but platinum-rhodium alloy resistance wire is expensive and cannot be measured repeatedly, and cannot adapt to industrial production.

In the current industrial production process, the synthesis temperature and pressure are mainly adjusted through the previous synthesis effect, so that only a rough adjustment can be made to the synthesis conditions.
