High Purity Graphite

High purity graphite is an ideal inorganic non-metallic material with high strength, good thermal shock resistance, high temperature resistance, oxidation resistance, low resistance coefficient, corrosion resistance and easy precision machining. It is used for manufacturing electric heating element, structural casting mould, crucible boat for smelting high purity metal, heater for single crystal furnace, graphite for EDM, sintering mould, anode for electron tube, metal coating, graphite crucible for semiconductor technology, graphite anode and grid for transmitting electron tube, thyratron and mercury arc rectifier.


It has the following characteristics:

1) Excellent self lubrication and low ash content;

2) Good chemical corrosion resistance;

3) High thermal conductivity and thermal stability;

4) Sufficient mechanical strength and impact resistance;

5) Easy to machine, can be processed into a variety of geometric products.
