ABSTRACTResults of further studies on phase equilibria in system CaO—ZrO2—TiO2 along the “pyrochlore” line ( Ca Zrx Ti3-x 07 ) are reported concerning the possible substitution of cerium for either calcium or zirconium in nominal “Ca Zr2 Ti 07”. The dominant tetragonal phase in this composition was identified as calzirtite. The structural role of zirconium and its tendency towards 7—coordination environments are discussed. Possible implications on high—level nuclear waste immobilizers like SYNROC are brieflyconsidered.
