Material Specification for YSr:123; [Y-Sr-Cu(Ti)-O] Process: Solid State Reaction
Notes: "Starting materials were high purity (>99.9%) Y2O3, SrCO3, CuO, Li2CO3, Al2O3, TiO2, V2O5, Cr2O3, Fe2O3, Co2O3, Ga2O3, GeO2, MoO3, WO3 and ReO3. They were weighed out in appropriate molar proportions and mixed through grinding in a mechanical mortar and pestle for 1 h. After an initial reaction at 1040-1060 °C in alumina crucibles, samples were reground, pressed into pellets, and heated in an O2 flow for 20 h at the same temperature ... Some of these samples were post-annealed at an oxygen partial pressure of 40 MPa and 1000 °C for 6 h, employing an oxygen Hot Isostatic Pressing (O2-HIP) apparatus made by Kobe Steel. ... Oxygen content (y) in the compounds was measured using the carbon-reduction method (Horiba, EMGA-650)."

Material Specification for YSr:123; [Y-Sr-Cu(W)-O] Process: Solid State Reaction
Notes: "Starting materials were high purity (>99.9%) Y2O3, SrCO3, CuO, Li2CO3, Al2O3, TiO2, V2O5, Cr2O3, Fe2O3, Co2O3, Ga2O3, GeO2, MoO3, WO3 and ReO3. They were weighed out in appropriate molar proportions and mixed through grinding in a mechanical mortar and pestle for 1 h. After an initial reaction at 1040-1060 °C in alumina crucibles, samples were reground, pressed into pellets, and heated in an O2 flow for 20 h at the same temperature ... Some of these samples were post-annealed at an oxygen partial pressure of 40 MPa and 1000 °C for 6 h, employing an oxygen Hot Isostatic Pressing (O2-HIP) apparatus made by Kobe Steel. ... Oxygen content (y) in the compounds was measured using the carbon-reduction method (Horiba, EMGA-650)."
