The main role of carbon graphite felt felt under vacuum or inert atmosphere by more than 2000 ℃ high temperature treated graphite felt, carbon content than high carbon graphite felt to sell more than 99%. The late 1960s the world has graphite felt the supply of goods. Graphite felt due to the choice of different raw mat into PAN-based graphite felt and glue-based graphite felt two. The PAN-based carbon fiber felt or rayon-based carbon felt cut to the desired size, rolled into a tubular graphite into the material of the container, the container placed in a high temperature furnace graphite (graphite tube furnace for high temperature furnace, IF, high frequency induction furnace or other heating forms of high-temperature furnace), with a vacuum or inert gas through high purity, to 100 ~ 300 ℃ / h heating rate of heating to 2200 ~ 2500 ℃ Lacey graphite, and then naturally cooled to 100 ℃ that is, too. Graphite is an allotrope of elemental carbon, carbon atoms surrounding each link with the other three carbon atoms (the arrangement was more of a hexagonal honeycomb-like) covalently bonded to form a covalent molecule. Since each carbon atom will emit an electron, that electrons can move freely, and therefore belong to the graphite conductor. Graphite is one of the softest mineral, its uses include the manufacture of pencil lead, and a lubricant. Carbon is a nonmetallic element, located at the second cycle Group IVA of the periodic table. Latin for Carbonium, meaning "coal, charcoal," graphite, the Chinese character "carbon" word from next charcoal "charcoal" word plus word stone structure, from the "charcoal" pronunciation. With the rapid development of China's metallurgical, chemical, machinery, medical equipment, nuclear power, automotive, aerospace and other industries, these industries demand for carbon and graphite products will continue to grow, our graphite and carbon products industry will maintain rapid growth . According to "China graphite and carbon products industry development prospects of strategic planning and investment analysis report Prospects" Statistics, 2006-2011, China's carbon and graphite products industry sales compound annual growth rate of 36.56%. According to the current domestic and international economic situation, combined 2006-2011 China graphite and carbon products industry sales data and Chinese economic growth data Lacey graphite prices, a rough estimate for 2012-2015 of graphite and carbon products industry sales compound annual growth 21%, in 2015, China's carbon and graphite products industry sales will reach 340 billion yuan.
