The high-temperature superconductor Sr1-xCaxCuO2 was synthesized using sol-gel, solid-state reaction and co-precipitation methods. The analysis of its formation was made and the structure of the products was determined with the help of the X-ray diffraction. The termal processes, that take place during the synthesis, were analyzed with the help of differential-termal analysis. The experiment has showed that the SrCuO2 formes in the the process of heating the citrats precursors at the temperature of 800oC. And the S0,5Ca0,5CuO2 formes at 900oC by sol-gel, solid-state reaction methods. The best results are achieved using citric gel precursor at the temperature of 900oC. The increase of heating duration up to 36 hours, made no considerable diference in the qualitative composition, however this has changed the quantitative composition.
