Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especiallycrucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.
