Abstract
Sintering, microstructure, and linear thermal expansion properties of Synroc-B and constituent phases, viz. perovskite CaTiO3, zirconolite Z rTi2O7, hollandite (ideal formula BaAl2Ti(6)O(16)) have been investiga ted. Synroc-B powder when pelletized and sintered at 1250 degrees C fo r 2 h achieved >95% theoretical density. Sintered Synroc-B has a linea r thermal expansion coefficient alpha of 8.72 x 10(-6) K-1 and Vicker' s microhardness 9.88 GPa. The linear thermal expansion curves did not show any hystersis indicating the absence of microcracking in the sint ered bodies.
