Materials and Properties

Dy:123; [Dy(Pr)-Ba-Cu-O]
Material Specification for Dy:123; [Dy(Pr)-Ba-Cu-O] Process: Solid State Reaction
Notes: "... samples... were synthesized by solid-state reactions from high-purity Dy2O3, Pr6O11, CaCO3, and CuO. Thoroughly mixed ingredient powders for each sample were first calcined in air at 900 °C for 12 h. The product was reground and pelletized for two consecutive sintering processes of 940 °C for 12 h each. Following the second sintering the sample was slowly cooled in 3 h to 600 °C for a 4 h annealing in flowing oxygen, cooled again in 2 h to 400 °C for another 8 h annealing, and finally cooled in 3 h to room temperature."
