Abstract
The relationships between thermal expansion and density, microcracking , stress and phase transition in K1/2Sr1/4Zr2P3O12(K2) and with K2 con taining 2 mass fraction of MgO (K2M2) have been studied. The materials showed a little thermal expansion anisotropy, hysteresis, and microcr acking. Thermal shock-induced cracks resulted in a decrease of the coe fficient of thermal expansion. Phase transition caused crack healing r esulting in a decrease in specimen size.
