The Intensified Competition Of Photovoltaic Market For International Graphite Enterprises

With the rapid development of the global solar photovoltaic industry,the demand for isotropic graphite is rapid growth.the demand of global isotropic graphite in 2010 has reached 40,000 tons,and the estimated demand will increase at average 25% to 30% growth rate every year in the future.for the new market,International Graphite Enterprises such as TOYO TANSO Japan、Tokai Carbon、SGL CARBON have expanded production capacity or built new production plant,Currently the output of global isotropic graphite for those graphite manufacturers are about 47000 tons/year.

Tokai Carbon Japan has already explored the further plans for the production capacity of isotropic graphite and it has been working for device expansion and reconstruction project.the demand of solar cells has expanded,Tokai Carbon Japan also plans to expand the production capacity of isotropic graphite to 15000 tons in the future.

Due to the features of high strength、high density etc,when used the graphite machining parts is heated evenly and can effectively reduce the internal stress produced by thermal shock.because they can greatly prolong the service-life of equipments or instruments,so widely used in the solar cell and semiconductor wafer industry.
