Zusammenfassung:	PURPOSE:To execute high density compression to a composite material by arranging gap through which granule of a material to be compressed does not pass but lubricating liquid passes at between a die and punches in a high isostatic pressing machine. CONSTITUTION:At the time of compressing the material to be compressed by incorporating the material to be compressed into the dies 3 in the pressing machine as surrounding this with the pressing medium and descending the punch 1, mixture of the granule of ceramic and metal and the lubricating liquid of oil, grease, etc., is used as the pressing medium. Then, at between the die 3 and the punches 1, 2, the gap having size, through which a large part of the granule does not pass but the lubricating liquid passes, is arranged. By this method, the high isostatic compressing work under the room temp. and high temp. can be executed to obtain the high compressed density product.
