[Abstract]:The recently developed two-stage 6-8 large cavity static high pressure device can be used to synthesize centimeter samples under the pressure above 15GPa. The design and experimental test of the high pressure cavity internal heating element of this device have been carried out. The relationship between heating power and temperature at different chamber pressure was calibrated, and the temperature and pressure conditions of the device were verified by the synthesis experiment of hexagonal boron nitride in the absence of catalyst. The experimental results show that the designed heating assembly works stably at high pressure and high temperature, and can be treated at high temperature and high pressure of centimeter grade samples under pressure over 14 GPA and temperature over 1 800 鈩，
