Natural graphite is a strategic mineral resources

1 graphite and products have become high-tech industry base material

Natural graphite and rare earths , as the " Industrial MSG " in the title , graphite new materials have become an important part of the emerging industry , a strong industrial relevance , expanded graphite , isotropic graphite , graphite fluoride , lithium-ion battery graphite anode material, metal - graphite composite materials have been widely used in energy-saving and environmental protection, new energy, new generation of information technology, new energy vehicles , high-end equipment manufacturing , new materials industry and other emerging industries. 2010 , the European Commission as one of the graphite " vital raw materials for the EU " 14 kinds . 2013 , graphene and the human brain works selected for the EU " Future Emerging Technology Flagship Project " , a special development program each receive 1 billion euros of funding .

2 natural graphite mineral resources of oligopolies

Graphite materials into natural flake graphite ( crystalline graphite ) , natural amorphous graphite ( graphite Aphanitic ), artificial graphite ( mainly raw petroleum coke and pitch coke ) three kinds . According to USGS data , the world's reserves of 71 million tons of natural graphite , Chinese reserves of 55 million tons , accounting for 77 % of the world , which accounts for crystalline graphite reserves worldwide 2 / 3 Aphanitic graphite resource accounting World 1 /10.

Although in many areas , natural graphite and artificial graphite is not very different . However, because of its excellent natural graphite characteristics , a certain irreplaceable. For example , Aphanitic graphite due to its own physical properties , is doing the best isotropic graphite materials ; in terms of expanded graphite , artificial graphite crystalline graphite can not be replaced ; in flame , the stability is not only the physical properties of natural graphite products , also not like other phosphorus-based flame retardants , chlorine , bromine-based and other harmful substances.

3 . Strategic value of natural graphite with technological advances constantly improve

Such as metal - graphite composite material not only has the properties of metal matrix, but also full of graphite , especially high purity graphite self-lubricating , high chemical stability , good shock absorption , thermal conductivity , low coefficient of linear thermal expansion characteristics, in aerospace, metallurgy, machinery , and other fields have a wide range of uses . The latest development of future applications of graphene even greater space , graphene can replace silicon material used in chips , the chip speed to THZ level. According to the agency estimated that the global annual demand for semiconductor crystal silicon is about 2500 tons , if the alternative to crystalline silicon graphene 1/10 made ​​of high-end integrated circuit , the market capacity of at least 5,000 billion yuan. Graphene is made of super- capacitors, charging time of just 1 ms. 2010 global ultracapacitor market size of 50 billion dollars, and maintain 20% growth rate .
