The isostatic gaphite rod and block formed by means of cold isostatic pressing (CIP) technique, isostatic graphite is characterized by its homogeneous structure and excellent isotropic electrical, thermal and mechanical properties. Its features are as following: Fine grain; Homogeneous structure; Isotropic properties;High density and high mechanical strength;High thermal and chemical resistance;High resistance to thermal shock; Proper electrical conductivity;Higher oxidation resistance; Lower ash content. Sometimes it is purified in special-designed graphitization furnace to remove non-carbonaceous impurities. It is widely used in various industrial and scientific engineering as a structural and/or functional material. The graphite block rod can be used for making graphite plate, graphite tube, graphite crucible, graphite rotor and shaft and so on. It widely used in electron industry, chemical…

Graphite is an allotrope of elemental carbon around each carbon atom connected with the other three carbon atoms (the arrangement of a plurality of hexagonal honeycomb type) by covalent bond, covalent molecular composition. Because each atom emits an electron, the electrons are free to move, so the graphite belongs to the conductor. Graphite is one of the softest minerals, and its uses include the manufacture of pencil cores and lubricants. Found that graphite parts life tend to be much shorter than expected life often in the production of silicon, due to the replacement of graphite device number and electric energy consumption of the graphite calcinations, in addition to increase production cost of enterprise, but also restricts the effective capacity of…

Graphite is soft, black and gray; greasy, polluting paper. The hardness is 1~2, and the hardness increases to 3~5 with the increase of impurity in the vertical direction. The specific gravity is 1.9 ~ 2.3. The specific surface area is concentrated at 1-20m2/g, and the melting point is above 3000 degrees under the condition of oxygen isolation. It is one of the most temperature resistant minerals. It can conduct electricity and conduct heat. According to these characteristics, graphite products are widely used in the following industry areas: 1, refractory material: graphite and its products have the properties of high temperature resistance, high strength, in the metallurgical industry is mainly used to manufacture steel commonly used in graphite crucible, graphite as…
