1, For the refractory material: graphite article having properties of high temperature and high strength, the metallurgical industry mainly used to manufacture a graphite crucible, commonly used in the steel ingot of graphite as a protective agent, a metallurgical furnace lining. 2, As the conductive material: the electrode, the cathode brushes, carbon rod, carbon tubes, mercury positive converter, graphite gaskets, phone parts, television picture tube coatings used for manufacturing in the electrical industry. 3, For wear and lubrication materials: graphite as a lubricant in the machinery industry often. Lubricants are often not on the premise of high speed, high temperature, high pressure use, and the wear-resistant material may be graphite (a) 200 ~ 2000 ℃ temperature at high sliding speeds,…
Graphite is one of the highest boiling point substances in nature melting, melting at 3 850 ± 50 ℃, boiling point is 4 500 ℃, and the boiling point of silicate minerals are 2 750 ℃ (quartz boiling point) or less, well above the boiling point of graphite impurities contained in the boiling point of the silicate. This feature is the basis of high-temperature purified graphite reason perish. The graphite powder directly into a graphite crucible and heated in inert gas and freon protective gas purification furnace to 2 300-3 000 ℃, a period of time, impurities in the graphite will overflow to achieve graphite purification. High-temperature method commonly used by flotation or more chemically purified 99% of the carbon-carbon…
Graphite specially processed later, you can create a variety of special materials for the relevant industrial sectors. With the development of modern science and technology and industry applications of graphite is constantly expanding, and has become an important raw material in the high-tech field of new composite materials, has an important role in the national economy. Here are some common graphite deep processing products: (1) High-purity graphite: widely used in nuclear reactor shielding and reflective materials, solid fuel, rocket nozzles, aerospace equipment parts, advanced refractory and paint, pencil of light industry, electrical industry, carbon brush, electrode in battery industry, fertilizer industry catalyst. (2) Graphite milk: milk into a graphite tube, forging graphite milk, milk graphite drawing, saving energy and reducing…
