Graphite is an allotrope of carbon, each carbon atom in the peripheral connecting also three carbon atoms (arrangement is multiple hexagon honeycomb) by covalent bonds with the covalent molecule is formed. Since each carbon atom emits an electron, the electrons can move freely, so that the graphite belongs to the conductor.. Graphite is one of the most soft minerals, and its use involves making pencil and lubricant.. Carbon is a non-metallic element, Latin Carbonium. Graphite and its products has high strength, acid resistance, corrosion resistance and high temperature resistant, 30 DEG C and resistance to low temperature - 204 DEG C and other excellent properties, is widely application in metallurgy, chemical industry, petroleum chemical industry, high energy physics, aerospace, electronics…
Low density carbon/graphite material has a good physical and chemical properties, in recent years,the study on the low density graphite material is very active.The expanded graphite block made of flexible graphite sheet,is also one kind of the low density graphite material. The method to make the expanded graphite block can be simply describe as below: Make the flexible graphite sheet dipped in the concentrated sulfuric acid and concentrated nitric acid,then,under the situation of 200℃～750℃ to make the expanded graphite block. The intercalator,dipping time,shape of the flexible graphite sheet and the operating temperature all have an influence on the density and shape integrity of the expanded graphite block. The density will be lower with the rise of operating temperature, but the…
Graphite blocks is the widely used graphite material and be used in many industies , from the material it can be divied into carbon blocks and graphite blocks , the difference is if the blocks is with the procedure of the graphitization . and for the graphite blocks , from the moulding method , it can be divided into three major kinds , isostatic graphite blocks , moulded graphite blocks and vibracation graphite blocks . Graphite Blocks are widely used in the Tooling (EDM), Mould making (EDM), and General Manufacturing industries. We can make it up to 3600mm long and 850 wide and 850 tall. The blocks are available in various specifications and size are as per different construction applications.…
