With the rapid development of the solar photovoltaic industry, the demand for its import and export raw materials monocrystalline silicon cells and polycrystalline silicon cells is increasing. In recent years, monocrystalline silicon processing plants and polycrystalline silicon processing plants with large-scale production have sprung up like bamboo shoots; Therefore, the raw and auxiliary materials required for the production of monocrystalline silicon and polycrystalline silicon are also increasing rapidly. Many raw and auxiliary materials in the photovoltaic industry need stable performance, and high-purity graphite is an important one of these raw and auxiliary materials. The development of high-purity graphite also promotes the production of high-quality monocrystalline silicon and polycrystalline silicon. Therefore, high-purity graphite plays an important role in the photovoltaic industry. High purity graphite is applied in the whole photovoltaic industry from silicon ore smelting to polysilicon production, and then to polysilicon ingot and Czochralski single crystal.
