Graphite is most
common in marble, schist or gneiss, due to its special structure, with many
features high temperature resistance, thermal shock resistance, electrical
conductivity, lubricity, chemical stability and plasticity,
is the modern
industrial and military high, new, sharp technological developments are an
important strategic resource. Experts had said, "The 20th century was the
century of silicon, the 21st century will be the century of carbon."
From the distribution
of resources situation exists, Asia, Europe, Africa, the Americas , Oceania
has a graphite deposit, but the Asian production of graphite most. According to
USGS statistics, the world's graphite resources proved reserves of
approximately 84 million tons, of which China reserves of 64 million tons,
accounting for 74% of the world's total reserves. 2010 global production of
about 925,000 tons, of which China
output of 600,000 tons, accounting for 64.9% of global output. Due to the lack
of regulatory industry disorderly competition leads to serious waste of
resources. However, this situation is expected with the implementation of
access conditions change.
According to the
U.S. Geological Survey, in 2011 the major downstream industry needs in the graphite refractory crucible 33% (China more than 40%), casting and steel manufacturing
accounted for 26%, 7% of the brake lining, battery and lubricant 5%, 29% for
other purposes.Access conditions put forward, "Twelve Five" period,
based on domestic demand, and strictly control the incremental, focusing on
optimizing inventory, actively adjusting structure, promoting mergers and
acquisitions, increased industrial concentration.
