The invention relates to the technology for producing of optically translucent ceramics. A method for producing of yttrium oxide ceramics comprises pressing yttrium oxide nanocrystal powder by the method of cold isostatic pressing with further sintering of produced sample and atmospheric cooling to room temperature. As istarting material the nanocrystal powder with particles size within range of 5-60 nm is used, pressing is carried out in vacuum under the pressure of 95-180 MPa, and sintering is carried out under the temperature of 760-800 °C for 20-30 minutes. The method allows to produce yttrium oxide ceramics at relatively small energy consumption with transmission of at least 85 % in visible range, and with density of 98-99 % relative to the single crystal density.
