High Purity Graphite

High purity graphite

High purity graphite refers to graphite with a carbon content greater than 99.99%. High-purity graphite has the advantages of high temperature resistance, corrosion resistance, thermal shock resistance, small thermal expansion coefficient, self-lubrication, small resistivity and easy machining.

Application

It is used in metallurgy, machinery, environmental protection, chemical industry, electronics, medicine, military industry and aerospace, and plays an increasingly important role in the national economy, especially in the solar photovoltaic industry.

In Future

The global solar photovoltaic industry has an average annual growth rate of 40%. China, as the world's largest solar photovoltaic producer, accounts for 70% of the world's total. The industry consumed more than 23,000 tons of high-grade graphite materials in 2011. It is expected that the demand for high-purity graphite materials for monocrystalline silicon and polycrystalline silicon in the photovoltaic industry will increase at an annual rate of 20% to 25%.
