The superconducting material Y Ba<sub>2</sub>Cu<sub>3</sub>O<sub>7−x</sub> was prepared by microwave heating of an oxide mixture (Y<sub>2</sub>O<sub>3</sub>, BaO, CuO). The time required for the synthesis is reduced to about 3.5 h compared to 1–2 days if conventional heating is used. If during the microwave heating the boat containing the starting powders is surrounded by SiC, the Y<sub>2</sub>BaCuO<sub>5</sub> insulating phase does not appear.
