FIELD: production of compact materials. SUBSTANCE: method for production of compact material consists in filling granules into container made of material with melting point below the temperature of final gas-static compaction. Prior to final gas-static compaction, preliminary hot gas-static compaction is effected at temperature below the container melting point with holding for 4-12 h and pressure equalling pressure of final compaction. EFFECT: higher efficiency. 1 tbl
