 Abstract: A series of single crystals of Sr1-xCaxCuO2, x = 0.19-0.83, has been grown using a low cooling rate in a flux containing excess CuO. Values of the temperature gradient, amount of flux, soaking temperature, soaking time, crucible material and cooling rate have been optimized. The chemical compositions for the as-grown crystals were determined by means of energy dispersive X-ray analysis (EDS) in a transmission electron microscope and confirmed by electron probe microanalysis (EPMA), while the SrCuO2-type structure having orthorhombic symmetry is confirmed by high resolution transmission electron microscopy (HREM). Both the Ca/Sr ratios in the crystals and the unit cell constants vary with a linear relationship with the Ca/Sr ratios in the initial melt.
