2.High density,Excellent thermal conductivity
HOT PROMOTIONS OF HIGH PURE SILICON CARBIDE GRAPHITE CRUCIBLES,BOTTOM PRICES,STEADY QUALITY!
A crucible 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.
