The complete reaction pathway describing the degradation of YBa2Cu307\_, by ZrO 2 is determined. Initial dissociation of the superconductor into YzBaCuOs, CuO and BaCuO2 is in accordance with the YBaCuO ternary phase diagram. Subsequent decomposition of Y2BaCuO5 in the presence of CuO and ZrO2 yield
