The effect of sintering temperature variation on the superconducting properties of ErBa2Cu3O7 superconductor prepared via coprecipitation method.

The effect of heat treatment on the superconducting properties of ErBa2Cu3O7−δ (ErBCO) ceramic materials has been studied. The nano-metal oxalate precursor was prepared using coprecipitation (COP) method. The prepared materials were subjected to calcination process at 900 °C for 12 h and then sinter...
