the residue from coal tar oil that is separated by distillation extraction of light oil, carbolic oil, phenol oil, naphthalene,
Modification coal tar pitch is the residue from coal tar oil that is separated by distillation extraction of light oil, carbolic oil, phenol oil, naphthalene, anthracene. Using a tube furnace continuous distillation, it is black solid under normal temperature. It is no fixed melting point, and Heat softening and melting, density is .25~1.35g/cm3, it is a kind of Heterocyclic compound contains oxygen, nitrogen, sulfur elements, etc.
Mainly used in super high power electrode, the quality pre-baked anode and carbon block, and the high density and high strength graphite, ect.
