High Purity Graphite
We are one of big companies produced High pure graphite in China. The high pure graphite we produced has more merits. It have highly intensity could resists heat and knocking well thermo stable is a good oxidation the resistance coefficient is slight anti corrosive, easy to precise machine adds and so on. It is an ideal non metals material.
The high pure graphite could be used to manufacture:
- Electric heating part
- The structure casting mould
- The crucible boat pan used to smelt the high fine metal
- The heater used to the unit crystal stove the graphite
- The agglutinated mould
- The wing
- The metal spreads plates
- The graphite crusher used to misconduct technology
- The thyratron
- The pool tube
- The graphite positive electrode and so on.
