Title: Densified carbonaceous bodies with improved surface finishes

Patent ·
OSTI ID:6774713

A method is described of producing a densified carbonaceous body with a superior surface finish, the method comprising the steps of: impregnating a permeable body composed essentially of a fine grained, isotropic graphite with a liquid impregnant containing furfural or furfural alcohol or a mixture thereof, an acid catalyst, and a pore-forming agent comprising a polyalkylene oxide adduct nonionic surfactant; heating the impregnated, permeable body to a temperature which is sufficiently high to polymerize the impregnant; and then heating the body to a temperature which is sufficiently high to pyrolyze the carbon in the polymerized impregnant.
