EuAl 3 (BO 3 ) 4 was synthesized using a conventional microwave in only 45 min. The sample temperature, measured with an infrared thermometer 5 s after the full cycle, was near 1000 • C. This procedure produced phase pure R32 EuAl 3 (BO 3 ) 4 . On the other hand, at- tempts to synthesize phase pure powder by conventional heating at 1000 • C invariably included EuBO 3 . Figure shows a powder XRD pattern for a microwave-synthesized sample. This is the first XRD-confirmed EuAl 3 (BO 3 ) 4 synthesis without a flux. At d = 5.69 Å and 2.85 Å, the pattern contains two partial domain peaks seen for the crushed crystals used to obtain Figure . The resolution was too low to determine if the peak at 1.96 Å was also present.
