We have various of graphite rods and blocks in different grades such as isostatic graphite, molded graphite,extruded graphite,vibrating graphite.

　　Isostatic graphite rods and blocks are widely used in medical treatment, metallurgy, chemical, airspace, and other industries, etc.We can provide different specification quality isostatic graphite rods: non-standard sizes can be designed and manufactured as per drawings or sample;high temperature and oxidation resistance, corrosion resistance, longevity;It is widely used in hot mineral and metallurgical and chemical industries.

　　The properties of the fine grain graphite rod and block:fine grain,homogeneous structure,

　　high density,excellent thermal conductivity;high mechanical strength;proper electrical conductivity;minimum wet tability to molten metals.

　　The high purity graphite means fine texture ,high purity-strength-density graphite products using the fine quality coke (low ash content) as its raw material.It is made in a scientific formula the process of mixing,pressing,baking and graphitization (above2500degrees).Therefore,it has the good properties of high temperature resistance,high electric and thermal conductivity.

　　High purity molded graphite is widely used in the electronic,mechanical and chemical industry etc.It can also be used as rectifier graphite anode ,mold for electronics agglomeration,constantly casting graphite crystallizer,accurate casting,the melting of semiconductor and rare metals,graphite crucible,mechanical seal in some fields as chemical industry, electrospark machining discharge anode,etc.

　　The application of our high density graphite block and rod:electrodes, anodes, cathodes, resistors, whisking rods, special structural parts, etc;Metallurgy, mechanical engineering;Chemical & electrochemical industry, glass & ceramics and other industries.

　　Graphite rod used in high temperature vacuum furnace as the heating body, the highest temperature can reach 3000 ℃,it is easy to be oxidized at high temperature, in addition to vacuum, it can only be used in the neutral atmosphere and reducing atmosphere.Its smaller thermal expansion coefficient, thermal conductivity, resistivity (8 ~ 13) x 10-6 Ω m., good workability with SiC, MoSi2 rods, high temperature resistant.

　　Pure graphite rod has high density, high strength, high purity graphite made, than ordinary graphite rod is to wear a little, but also relative wear resistance, some graphite products need to in the rotating device, so this requires ultra high pure graphite abrasion resistance, because there will be dust in repeated rotation friction thus, high purity graphite product itself is not very wear-resistant.

　　Gao Chunshi said the high purity materials simple ink manufactured by high purity graphite of high purity graphite rods with the same specific, high purity graphite rod belongs to artificial graphite, graphite powder is called asphalt binder or coal oil coke after high pressure extrusion molding machine, and then after several high-temperature roasting and impregnation, the inside of the graphite the adhesive has evaporated, and fill the gap by impregnation evaporation, so stomatal production and processing of high pure graphite rods, chlamydia, has the advantages of high density, high hardness, wear resistance, high strength characteristics.

　　Ordinary graphite cudgels pure graphite rod difference density and porosity of graphite rods, graphite rods without impregnation and calcination, is the use of graphite powder and binder extrusion molding, strength and density are very soft, falling dust, easy to loose. Greatly reduce the graphite conductive and lubrication characteristics. There is the use of graphite powder particles of different sizes, the graphite materials are of high purity graphite as raw materials for processing the high pure graphite graphite rod is used mostly recycled graphite powder, graphite powder is recycled some recycled graphite products used in pulverizing with binder molding, graphite powder so this impure, graphite raw materials produced graphite particles of coarse, large pores, trachoma and more. Mainly used for carbon arc gouging carbon rod cutting foundry, appearance is coated with a layer of copper to moisture conductive around.

　　Application environment of high purity graphite rod:

　　High pure graphite rod electrothermal commonly used in high temperature vacuum furnace body, a graphite rod maximum temperature is 3000 degrees centigrade, the graphite rods are easily oxidized at high temperature in vacuum, the graphite rods only in the neutral atmosphere or reducing atmosphere in use. Its lower thermal expansion coefficient, high thermal conductivity, resistance coefficient (8~13) * 10-6 Omega - m, SiC, MoSi2 processing is good, high temperature resistance, resistance to extreme heat is good, the price is cheaper.
