Description
The graphite heater components are used in the high temperature furnace with temperature reached 2200 degrees at vacuum environment and 3000 degrees in the deoxidized and inserted gas environment.
Main Features
1. uniformity of heating structure.
2. good electrical conductivity and high electrical load.
3. corrosion resistance.
4. inoxidizability.
5. high chemical purity.
6. high mechanical strength.
The advantage is energy efficient, high value and low maintenance.
We can produce anti-oxidation and long life span graphite crucible, graphite mold and all parts of graphite heater.
