Abstract

Phase transformation from perovskite to "post-perovskite" and reserve transition in CaRuO₃ was observed by in situ X-ray diffraction at pressure of 20-22 GPa and temperature of 1173-1523 K. These pressure and temperature conditions are 1-2 GPa lower than previous results by quenched method. The axial compressibility is estimated to be a/a ₀>b/b₀>c/c₀. This result is inconsistent with previous result on CaIrO₃.
