graphite saggar
Graphite saggers are widely used in experiments and metals, non-metal smelting.
They are also used for cathode materials such as battery lithium iron phosphate and carbon graphite anode materials carbonization.
They are excellent containers for graphitization and sintering.
Kimwan crucible and sagger are widely used in the metallurgy, foundry, machinery, chemical, anode materials andother industrial sectors for the smelting of alloy tool steel and the smeting of hon-ferrous metals and their alloys. lthas a good technical and economic effect.
1. Good thermal stability；
2. Excellent anti-corrosion resistance and shock resistance；
3. Good resistance to acid and alkali;
4. High thermal conductivity；
5. Pure graphite materials without pollution
Special graphite materials are selected for precious metal smelting. They can make graphite saggers two times more durable than ordinary materials with a longer service life and can withstand higher temperatures exceeding 2000 °C.
