    • A curved pyrolytic graphite crystal x-ray monochromator has at least one diffraction surface of graphite crystal for diffracting and monochromizing x-rays generated from an x-ray source so as to bend and/or converge the diffracted and monochromized x-rays, wherein the diffraction surface has a predetermined curved surface. In a method for manufacturing a curved pyrolytic graphite crystal x-ray monochromator, one or more pieces of polymer films are heated at a temperature predetermined in a range from 400.degree. C. to 3500.degree. C. so as to form carbonaceous films, and then, one or more pieces of formed carbonaceous films are superimposed, heated and pressed onto a predetermined curved surface of an isotropic graphite die at a temperature predetermined in a range from 400.degree. C. to 3500.degree. C., while applying a predetermined pressure onto the carbonaceous films provided on the isotropic graphite die, thereby forming the curved pyrolytic graphite x-ray monochromator of graphite crystal having a resulting curved surface corresponding to the predetermined curved surface.

    • A method for making a graphite sheet or block with a desired thickness which comprises hot pressing at least two films of a polymer selected from a polyoxadiazole, an aromatic polyamide and an aromatic polyimide at a pressure not lower than 4 kg/cm.sup.2 at temperatures not lower than 2200.degree. C. Prior to the hot pressing, the at least two films may be thermally treated at temperatures of not lower than 2200.degree. C. and subsequently hot pressed at a pressure of not lower than 4 kg/cm.sup.2 at a temperature of not lower than 2000.degree. C. when the at least two films are made of the polyoxadiazole or aromatic polyamide or at a temperature of not lower than 1600.degree. C. when the at least two films are made of the aromatic polyimide.
