Graphite crucible has good thermal conductivity and high temperature resistance. In the process of high temperature use, its thermal expansion coefficient is small, and it has certain strain resistance to rapid heating and rapid cooling. It has strong resistance to acid and alkaline solution corrosion and good chemical stability.

Graphite crucible with its excellent performance, widely used in metallurgy, casting, machinery, chemical industry and other industries of alloy steel, non-ferrous metals and their alloys smelting. Good technical and economic results have been achieved.

In the use of graphite crucible, often encounter some heater damage phenomenon, the device damage may be man-made or deterioration and other reasons, if it is man-made need to strengthen management, strengthen the staff's awareness of prevention, in the use of graphite crucible need to be handled gently, sometimes graphite crucible surface damage, this may be due to the impact during handling or the lack of moisture-proof treatment in the storage environment or the environment is not dry.
