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