Novel diamond thermal shock detection process

The invention relates to the technical field of diamond raw material detection, in particular to a novel diamond thermal shock detection process. Graphite mold containing cavity serial numbers are selected for diamond sample bags according to the arrangement sequence, one diamond is contained in two containing cavities, a sintering process is set, the diamond is sintered, the upper end face and the lower end face of the graphite mold are each provided with a graphite cushion block, the graphite cushion blocks are placed in the center of a sintering machine workbench, infrared temperature measurement is aligned with a temperature measurement point, and a sintering machine process strip section is selected; the heat preservation temperature is 900-1100 DEG C, the heat preservation time is 6-10 minutes, and the total time is 15-25 minutes; after sintering is completed, air cooling is conducted for 20-40 min; the tray is placed on an electronic balance, the cooled diamond is weighed through the electronic balance
