Abstract

The invention relates to the technical field of preparation of new materials, in particular to a germanium single crystal growth furnace and a germanium single crystal growth temperature control method based on the growth furnace. The germanium single crystal growth furnace is fixed on a base vertically and is characterized in that the growth furnace adopts a cylindrical stainless steel furnace body; several heating electrodes are arranged on the side wall of the furnace body from bottom to top; annular thermal insulation materials are arranged inside the furnace body; a support system is arranged at the bottom of a central shaft of the furnace body; a special-shaped quartz tube is erected on the support system; a lower crucible, a middle ring, an upper crucible and a sealing cap are sequentially arranged in the special-shaped quartz tube from bottom to top; quartz wool covers the special-shaped quartz tube. The growth furnace specific to the growth characteristics of 8-inch germanium single crystals is exquisite in structure and reasonable in design of temperature area.

Description

technical field [0001] The invention relates to the technical field of new material preparation, in particular to a germanium single crystal growth furnace and a germanium single crystal growth temperature control method based on the growth furnace. Background technique [0002] Germanium is a rare metal element, which is rare in nature and scattered in distribution. Due to its semiconducting properties, germanium is basically used in high-tech fields, such as electronics, optical fiber, infrared optics, and semiconductor materials. Very important strategic material. At present, the annual output of germanium in the world is about 200 tons. my country is one of the main producers of germanium, with a total of about 100 tons, accounting for about 50% of the world's total production. With the development of science and technology, its use continues to expand, and is now widely used in military, aerospace, communications, medicine and other fields, such as electronics industry...
