high-density graphite crucible so that the crucible has the best thermal conductivity, thermal conductivity other imported crucible;the graphite crucible and the appearance of a special glaze layer and forming a dense material, greatly improving the corrosion and prolong its service life;the graphite crucible graphite component used in graphite, thermal conductivity is very good. After heating the graphite crucible can not be immediately placed on a cold metal table, due to a sharp cooling in order to avoid it being broken.Mainly used in the purification of gold and silver smelting, metal casting special, university experimental equipment, acid corrosion of the crucible, the crucible temperature analysis, small scale casting, special alloy smelting casting mold and so on.SpecificationsMaterial:GraphiteOuter size:85x45X30mmInner size:65x30X20mmPackage Contents:1x 235OZ Melting crucibleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
