Aluminium Melting Graphite Crucibles have the following advantages:
Low coefficient of thermal expansion.
Good electrical conductivity.High radiation emissivity.High compressive strength.High resistance to erosion.Low friction; self-lubrication.High resistance to chemical attack and corrosion.High adsorption of gases and vapours.High moderating ratio; i.e. ratio of fast neutrons slowing-down power to bulk neutron absorption coefficiently.High ratio of thermal neutron scattering to absorption cross section.Bulk Density | g/cc | 1.70-1.88 |
