The synthesis of gadolinium aluminum perovskite (GAP ) in under 1 min via microwave irradiation is presented here. Pellets of the thus‐formed GAP transform into a translucent ceramic of very high fracture toughness upon sintering in the microwave oven. In contrast, conventional heating yields an opaque material. The Figure shows the microstructure of microwave‐sintered, polished, and etched GAP.
