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.
