A method of manufacturing ceramic cores from ytterbium oxide enriched in ytterbium-168 isotope is presented. This method is based on sintering ytterbium oxide powder under a high isostatic pressure of about 8 GPa in order to obtain its B-modification with a monoclinic crystal lattice structure. The equipment used, the sintering modes and the results of the analysis of the obtained samples are described, which, due to their high density (up to 10.2 g / cm 3 ), are promising for use as sources in contact radiation therapy of tumors
