graphite is a new type of material.Graphite block is used in precision tool,aerospace industry,war industry ,chemical industry etc..There are  Extruded Graphite,Molded Graphite, Vibration Graphite,High density and high Flexible Strength graphite material . (Die molded graphite),High pure extruded graphite, Special carburizing treatment graphite material. 

 Advantages of  graphite lining :

1,high strength,high hardness
2,good heat-resistance, low porosity 
3,anti-abrasion,anti-scour 
4,high purity graphite

Graphite plates have good resistance to thermal shock, oxidation and corrosion, and have suitable resistivity and homogenous structure. And it offers excellent sealing capabilities under extreme conditions with a longer life and less maintenance.
