Abstract In order to optimize the synthesis of BaCuO 2 , different modes were developed and estimated. Wet chemical powders produced by coprecipitation of oxalates or hydroxycarbonates were characterized and their reactivity is compared with the conventional ceramic process of firing a mixture of BaCO 3 and CuO by DTA, XRD and IR‐investigations. This becomes possible, because the decomposition of these chemical precursors to BaCO 3 and CuO is finished up to 600 °C. Hence, the same reaction for the formation of BaCuO 2 is monitored.
