GRAPHITE CRUCIBLE, HEATING FURNACE AND PREPARATION METHOD FOR CADMIUM TELLURIDE

摘要

Provided are a graphite crucible, a heating furnace, and a preparation method for cadmium telluride. The graphite crucible comprises: a crucible body; a crucible cover, matched with the crucible body; and a collar, connected with the crucible body fixedly and comprising collar grooves arranged along the circumference. The crucible cover comprises: a flange, protruding and stretching along the circumference and along the direction matched with the crucible body, so that after the graphite crucible is assembled, the flange is in the collar groove of the collar. Based on the graphite crucible, the heating furnace and the preparation method for cadmium telluride can achieve cost savings and safe operations and are environmentally friendly.
