Abstract
This paper describes ultrapurification of isotopically enriched calcium and molybdenum compounds and 40Ca100MoO4 calcium molybdate growth charge in order to remove radioactive uranium, thorium, and radium impurities. 40Ca100MoO4 single crystals grown from such charges are needed for the fabrication of scintillator elements of the cryogenic detector for the AMoRE project: a search for 100Mo neutrino-less double-beta decay.
