Graphite Melting Crucibles & Silicon Carbide Crucibles - …

The Silicon Carbide crucibles (SiC) are used when melting with our larger induction melting systems, they are durable, do not oxidize and break down as quickly as graphite. These types of crucibles are also used in some of our smaller furnaces in order to attain higher purity melts without the potential for graphite contamination.

Melting point - Wikipedia

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid.At the melting point the solid and liquid phase exist in equilibrium.The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
