Abstract
A two-phase glass-like carbon member has, in combination, a porous glass-like carbon base, and a dense glass-like carbon surface layer formed on the porous glass-like carbon base. The porous glass-like carbon base can be formed in a large thickness. The dense glass-like carbon surface layer is superior to the porous glass-like carbon base in gas impermeability, surface hardness and resistance to dusting. The dense glass-like carbon surface layer supplements disadvantages of the porous glass-like carbon base. The two-phase glass-like carbon member can be in a large thickness exceeding 5 mm and in a complicated shape.
