<p>An objective of the present invention is to provide a method of manufacturing a hafnium oxide-carbon series nanoparticle sintered body capable of selecting hafnium oxide having similar thermal conductivity properties as uranium oxide as a substitute, mixing and sintering carbon series nanoparticles, and then performing a test of estimating a thermal conductivity of uranium oxide. In order to accomplish this objective, the method of manufacturing a hafnium oxide-carbon series nanoparticle sintered body as a substitute for obtaining thermal behavior characteristics of a mixed sintered body of uranium oxide and carbon series nanoparticles comprises: a preparation step in which hafnium oxide powders, carbon series nanoparticle powders, a can, and a cover are prepared; a powder filling step in which the hafnium oxide powders are mixed with the carbon series nanoparticle powders and an inner portion of the can is filled with the mixed result; a sealing step in which a cover is welded on the can, the can is degassified, and a penetrating tube formed on the cover is sealed; a sintering step in which the can and the cover assembly are sintered; and a sintered body separating step in which the can and the cover assembly are separated from the sintered body.</p> |
