High purity graphite is a graphite with a carbon content of more than 99.99%. High purity graphite with high temperature resistance, corrosion resistance, thermal shock resistance, thermal expansion coefficient is small, self lubrication, resistance coefficient is small and easy to processing machinery, and other advantages, is widely used in metallurgical, mechanical, environmental, chemical, electronic, medical, military and aerospace fields, the position in the national economy is becoming more and more important, especially in the solar photovoltaic industry. The global photovoltaic industry average annual growth rate of 40%, China as the world's largest producer of solar photovoltaic, 70% of its share to the global, high-grade graphite materials consumed by the industry in 2011 reached 2.3 million T to expected future photovoltaic industry of silicon and polysilicon demand of high purity graphite materials will be at the speed of 20% ~ 25% a year growth
The future development direction of high purity graphite will be the production of structural and performance integration, and the comprehensive performance of a good product. At present, the production of high purity graphite defects and future requirements based on the need in the future research, strengthen academic exchanges between enterprises and international cooperation, cooperation, optimize some key technology, in order to obtain the best process parameters; in countries and jointly support the relevant enterprises, construction engineering technology center, actively carry out new technologies new product research and development work; International Association founded the production process of high-purity graphite, annual meetings, research progress of high purity graphite production process; to strengthen the basic theory research; using computer simulation technology to simulate and optimize the production process also will be the future development direction of hot spot.
