The price of graphene, known as "black gold", in the Chinese market is nearly 10 times that of gold, at more than 2,000 yuan per gram.On October 16 last year, the graphene composite conductive liquid project was officially launched in songbei and put into mass production.This means that our province's deep processing of graphite on a new level.Heilongjiang province natural graphite processing new technology and high-end application engineering technology research center research and development of graphite.

Graphite can be used in negative materials

Stimulated by the rapid development of the new energy vehicle market, the power battery expansion wave after wave, so that the negative material enterprises harvest a lot.According to a survey by GGII, China produced 72,800 tons of anode materials in 2015, up 42.7% year on year.The output value of domestic anode materials was 3.88 billion yuan, up 35.2% year-on-year.

Graphite can be used in solar photovoltaic graphite processing workpiece

involving solar photovoltaic industry we must mention graphite products.Graphite products are the carrier of solar photovoltaic industry, which are mainly used in monocrystalline silicon ingot manufacturing and polycrystalline silicon ingot manufacturing.Due to the density, hardness, compression resistance of isostatic graphite in the industry are better than other metal materials, with high temperature resistance, high pressure resistance, corrosion resistance, good electrical conductivity, stability and other advantages, the importance of graphite products in the solar wafer manufacturing process is particularly prominent.

Graphite products are closely related to the development of solar photovoltaic industry. At present, the quality of graphite products directly affects the quality of crystalline silicon pulling, and the quality of crystalline silicon has a direct relationship with the efficiency of solar cell conversion, so to ensure the quality of solar photovoltaic hot field graphite workpiece is the most important.In an ordinary solar thermal field, there are more than 20 important graphite workpieces. For example, in the process of pulling monocrystalline silicon, the quality of graphite crucible directly determines the use times of crucible itself.

Graphite atomic energy field

Graphite is used in atomic energy industry and military industry because of its good neutron deceleration performance, it was used as a deceleration material in atomic reactors earlier.Graphite reactor is a more atomic reactor.The graphite material used in atomic reactors must be of extremely high purity.Some specially treated graphite (such as high-temperature resistant material infiltrated into the surface of graphite), recrystallized graphite and pyrolytic graphite have better stability and higher strength to weight ratio at very high temperature.So they can be used to make nozzles for solid-fuel rockets, nose cones for missiles, and parts for space vehicles.
