Abstract

The formation and decomposition processes of the Ca0.5Sr0.5CuO2 high pressure phase with the so-called infinite-layer structure have been followed in-situ by energy dispersive X-ray diffraction using a synchrotron radiation source. The decomposition reaction of the infinite-layer phase is produced at 1200 °C to yield a mixture of phases including the n= 2 member of the Srn-1CunO2n-1 family and (Ca, Sr)2CuO3. This reaction implies a volume reduction and the most significant changes are observed in the a-b plane implying that the CuO2 planes are partially condensed.
