A @P04522@ with good graphitizability, characterized by a combination of properties which differ significantly from those of @M03866@ but do not reach the quality level of @P04814@. These properties are: optical @AT06776@, medium reversible thermal expansion and low ash content. Regular @C01142@ is mainly used for the production of synthetic carbon and @G02687@.
