Abstract:

We studied the possibility of synthesizing infinite-layer (IL) phases of Sr1-xLixCuO2 (0 < x < 1) composition from both orthorhombic Sr1-xLixCuO2 (0 < x < 1) Solid solutions and from the corresponding cuprates, SrCuO2 and Li2CuO2, at high pressures (P = 4-8 GPa) and high temperatures (T = 600-1000degreesC). The optimal conditions for synthesis of the IL phases are P = 4 GPa, T = 800degreesC, and tau = 2 min. At high pressures and temperatures, the components of the SrCuO2- LiCuO2 system show limited mutual solubility. Sr1-xLixCuO2 solid solutions exist at 0 < x < 0.15. The relationship between the unit cell parameters and Li content of high-pressure Sr1-xLixCuO2 phases has been established.
