The relationship between uhp 550 mm graphite electrodes and the solar photovoltaic industry

uhp 550 mm graphite electrodes

Carbon graphite products are the industrial basis for the development of the solar photovoltaic power generation industry, and the two coexist and prosper together. Carbon is used in the manufacturing of polycrystalline silicon ingots and monocrystalline silicon ingots in the photovoltaic industry. Because carbon density, hardness, and compression resistance are very good, it has the advantages of high temperature resistance, high pressure resistance, corrosion resistance, good electrical conductivity, stable performance, etc., in the upstream of the solar photovoltaic power generation industry-silicon wafer manufacturing, carbon graphite The material can be made into a heating container of silica material-graphite crucible, which can be used as a thermal field for drawing silicon rods and manufacturing silicon ingots.

For example, the graphite crucible is very close to the polysilicon melting and casting, which has a direct impact on the quality of the drawn single crystal rod, and its degree of influence is second only to the polysilicon itself. In the process of drawing single crystal silicon rods, the graphite crucible is attached to the quartz pot, and the quartz pot will be scrapped and updated every time the single crystal is drawn. The graphite crucible has a certain number of repeated uses. To be used repeatedly, this requires higher requirements.

If the material of the crucible is not good enough, impurities will be emitted from the graphite crucible at high temperature. During the single crystal growth process, once the impurities are mixed with it, the process is irreversible, and the quality of the ingot will be greatly reduced. Carbon produces a variety of graphite plates, graphite rods, graphite electrodes, graphite products, graphite boats, graphite crucibles, graphite processing and other products.
