Graphite Crucible Melting Pots - 1650°C high …

Description. Graphite crucibles are high temperature resistant containers used for melting or heating small items. Graphite is electrically conductive and therefore will be directly heated by our induction heater systems or can also be used in a furnace. If you wish to only heat metal parts inside the container, we also have non-conductive Corundum Crucibles available.

Why does graphite have a high melting point even …

2020-11-6 · Now melting is essentially turning a highly ordered state of molecules to a disorderly one. That comes at an expense of energy. In this case, since the constituent molecules of graphite are held together by a strong covalent force, a high amount of energy is needed to weaken that bond. That explains graphite's high melting point.
