Scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), and analytical electron microscopy (AEM) studies have been conducted on samples crystallized from melts with a composition of zirconolite {(Ca[sub 0.9]Gd[sub 0.1])Zr(Ti[sub 1.9]Al[sub 0.1])[sub 2]O[sub 7]} and CaCeTi[sub 2]O[sub 7]. The formation of a whole suite of Synroc phases (zirconia, ZrTiO[sub 4], zirconolite, perovskite, and rutile) has been observed. © 2000 American Institute of Physics.
