摘要： Graphite blocks are produced by a process wherein one or plural polymer films having a thickness of from 1 to 400 .mu.m and selected from aromatic polyimides, aromatic polyamides and polyoxadiazoles are heat treated to obtain carbonaceous films. A plurality of the carbonaceous films are hot pressure under certain conditions to obtain thick graphite blocks. The blocks have a remarkably improved rocking characteristic and are useful as radiation optical elements such as X-ray or neutron ray monochromators or filters. The blocks may be curved to obtain bent-type graphite articles.

摘要： A process for producing a graphite block from a plurality of graphitizable polymer films or a plurality of carbonaceous films separately obtained from graphitizable polymer films is described. The method comprises superposing the plurality of the graphitizable polymer films or the plurality of the carbonaceous films, and thermally treating the plurality of the graphitizable polymer films or the plurality of the carbonaceous films in a substantially compression pressure-free condition when the treating temperature is in the thermal carbonization temperature range and the graphitization temperature range and under compression pressures in temperature ranges between the thermal carbonization temperature and the graphitization temperature ranges and over the graphitization temperature range. The compression pressure over the graphitization temperature range should be higher than that in the range between the thermal carbonization and graphitization temperature ranges. By this, a wrinkle-free graphite block with a good rocking characteristic is obtained.

摘要： Optical elements for radiation comprising a graphite film obtained from a film of a polymer such as polyphenylene oxadiazole, polybenzothiazole, polybenzobisthiazole, polybenzooxazole, polybenzobisoxazole, polypyromellitimide, polyphenylene isophthalamide, polyphenylene benzoimidazole, polyphenylene benzobisimidazole, polythiazole or poly-p-phenylene-vinylene. The graphite film is obtained by pyrolysis of the polymer film at 2800.degree. C. or higher at a pressure of not lower than 4 kg/cm.sup.2 in vacuum or in an inert gas. Alternatively, the element may be made of a graphite film obtained from the polymers mentioned above and intercalated with a metal halide. The intercalated films are readily bonded by pressing in the form of a thick sheet or block. Still alternatively, the graphite films and the intercalated films may be superposed alternately and bonded by pressing, or the intercalated films may be sandwiched between the graphite films and bonded together to form a thick sheet or block. The optical element has application as a lens, monochromater, filter or analyzer for radiations.
