CONSTITUTION:A powder compact and epoxy resin undergo degassing in vacuum. During this period, the powder compact is heated to about 200 deg.C in order to evaporate the adsorbed material in the surface of power. Then, the powder compact is cooled, and the powder compact and the epoxy resin are brought into contact. The atmosphere is returned into the atmospheric pressure, and the epoxy resin is infiltrated into the inside of the powder compact. After the epoxy resin is solidified, the powder compact is polished. The epoxy resin is brought into contact with a part of the exposed cross section, wherein the epoxy resin is not infiltrated, in the vaccum state. Pressure is applied, and the pressure is maintained until the resin is solidified. After the resin is solidified, the surface to be evaluated is finished as the mirror surface and exposed. The intensity of the characteristic X rays of uranium element at the exposed surface is measured by an energy dispersion type X-ray analyzer, and the relative density is obtained.
