Abstract

The invention discloses a graphite heating body and a crystal growth furnace. The graphite heating body comprises a graphite body and at least two electrode portions, and the graphite body comprises aheating bottom wall and a heating side wall; the heating side wall comprises at least four heating side plates, and every two heating side plates form a side wall heating portion; the heating bottomwall comprises at least two heating base plates, the heating base plates are spaced from each other, and the second ends of every two adjacent side wall heating portions are connected by the corresponding heating base plate; the electrode portions are respectively arranged on the different side wall heating portions. The graphite heating body and the crystal growth furnace can be applied to solvethe problem of high cost of the KY crystal growth process.

Description

technical field [0001] The invention relates to the technical field of crystal growth, in particular to a graphite heating element and a crystal growth furnace. Background technique [0002] At present, in the field of crystal growth, especially in the field of high-temperature crystal growth, most refractory metals such as tungsten and molybdenum are used as heating elements and insulation layer materials. Although refractory metals have high melting points, strong corrosion resistance, simple processing technology, and low production costs, etc. , but in practical applications, resulting in high energy consumption of crystal production equipment. For enterprises that carry out large-scale crystal growth, the consumption of electricity is the main cost expenditure, and the use of refractory metal materials is not conducive to the reduction of production costs for enterprises, and the refractory metal materials used in crystal growth furnaces, whether they are heating elemen...
