Carbon & Allied Products
The Manufacture and uses of carbon
Common raw materials for carbon manufacture are petroleum coke, retort coke, graphite, carbon black and anthracite. These raw materials are ground to powder and graded for size. These powders together with binders, are mixed in heated container. This mixed powder turns into Blanks by compress’ive pressure, extrusion or isostatic pressure. The pressed material is heat treated in kilns and this process carbonizes the binder and hard carbon is produced. This hard cabon is again electrographitised and impregnated with resins or metal, as application demands, which results in an increase in strength, greater impermeability and higher wear resistance. The types raw materials, their grain size and processing conditions influence, within certain limits, the final mechanical, thermal and electrical properties of the carbon.
