The application of graphite in the field of solar photovoltaic power generation is mainly concentrated in the manufacturing of polysilicon raw materials, drawing of single crystal silicon rod and casting of polysilicon ingot. Because the density, hardness and compression resistance of carbon graphite material are very good, it has the advantages of high temperature resistance, high pressure resistance, corrosion resistance, good conductivity and stable performance. It is in the upstream of solar photovoltaic power generation industry - silicon wafer manufacturing ring The carbon graphite material can be made into the heating vessel of silicon stone - graphite crucible, which can be used as the heat field for purifying polycrystalline silicon, drawing silicon rod and manufacturing silicon ingot, and also can be made into the "cushion" used in the process of crystalline silicon slicing. Because of the excellent performance of carbon, these carbon graphite material products undoubtedly become the manufacture of key equipment upstream of the solar photovoltaic power generation industry chain Build the foundation.

In the semiconductor industry, more than 98% of electronic components are made of monocrystalline silicon, while the Czochralski furnace is made up of graphite heater and graphite insulation sleeve. Most of the thermal field of ingot polycrystalline silicon is made of high-purity graphite and high-purity carbon felt insulation materials. Graphite is also a necessary auxiliary tool and component in the processing of semiconductor silicon wafer.
