Compared with metal materials and other ceramic materials, high-purity graphite products have unique properties and can be used in various industries, including semiconductors. Especially, our high-purity graphite material contains less than 3ppm of ash and is widely used in heaters and crucibles, for drawing monocrystalline silicon and for liquid-phase epitaxial growth in semiconductor manufacturing processes. In addition, graphite product suppliers are renowned worldwide as sensors for epitaxial growth and other fixtures.

The global solar photovoltaic industry has an average annual growth rate of 40%, with China accounting for 70% of the world's total, making it a country in the global solar photovoltaic industry. In 2011, the industry consumed over 23000 tons of high-grade graphite materials, and it is expected that the demand for high-purity graphite materials from monocrystalline and polycrystalline silicon in the photovoltaic industry will grow at a rate of 20% to 25% annually in the future. At present, China's graphite industry is still at a low level in the world, with products mainly consisting of raw materials and primary processing products. The high impurity content in the products limits their application.

Therefore, on the one hand, the low price of graphite in China leads to a large export volume; On the other hand, the domestic market requires high-purity ultrafine graphite products, mainly imported from abroad. In summary, conducting research on the production technology of high-purity graphite and improving product quality is very important for China's high-purity graphite industry.
