Today, six-punch high-pressure apparatus of cubic type are perspective for growing single crystals of diamond by the temperature gradient method. Experimental determination of the temperature distribution in the growth volume takes a lot of time and effort, so it is rational to use computer modeling. With the help of the ANSYS Workbench software, a technique has been developed for simulating temperature fields in six-pound HPA, depending on the mass concentration of graphite in the composite heater. It is established that a change in the concentration of graphite from 5 to 50 % allows one to vary the temperature at the characteristic points of the high-pressure chamber by 26–170 °C, the horizontal and vertical temperature drops in the growth volume by 66–69 °C and the temperature gradients in it by 3.8–14 deg / mm. |
