Notes:
Melt spinning has been used to prepare superconducting R-Ba-Cu-O compounds with R=Y, Er, Dy, and Gd. The starting materials were sintered R-Ba-Cu-O samples, and most of them were not superconducting above 77 K. The melt-spun samples had a spherical shape with a diameter in the range of 0.1–2.0 mm. The samples were annealed in air at about 900 °C for 1 h. Samples with diameter greater than 1.5 mm were found to be not superconducting. The critical temperatures were found to be in the range of 60–88 K.
