摘要

Various combinations of calcination temperature and oxygen partial pressures have been investigated to stabilize the infinite-layer structure in Ca1-xSrxCuO2 and (Ca1-x-yYy)SrxCuO2 systems using a solid-state reaction method. It is found that the stability of infinite-layer structure for different compositions strongly depends on the calcination conditions. The infinite-layer structure is stable in the range of 0.12 ≤ x ≤ 0.16 for Ca1-xSrxCuO2 at the calcination conditions of 940°C and 3% partial pressure of oxygen, and also in the range of 0.08 ≤ x ≤ 0.12 at the calcination conditions of 1020°C and 1 atm of flowing oxygen. The solubility limit extends to the range of 0.10 ≤ x ≤ 0.20 for y = 0.02 in Ca1-x-yYySrxCuO2 prepared at 940°C under 3% partial pressure of oxygen.
