Graphite crucible has good thermal conductivity and high temperature resistance. It has small thermal expansion coefficient and has a certain strain resistance to hot and rapid cooling in the process of high temperature use. The corrosion resistance of acid and alkaline solution is strong, and it has excellent chemical stability. It is widely used in metallurgy, casting, machinery, chemical industry, smelting of alloy tool steel and smelting of nonferrous metals and their alloys, and has better technical and economic results. Our company can machine all of the sizes the graphite crucibles for different application with the molded graphite or isostatic graphite materials. We can machine the graphite crucibles according to the customer’s dimension requirements or drawings accurately. Many of the…
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…
