YBCO Oxalate Coprecipitation in Alcoholic Solutions

A process for synthesis of ultrafine YBa2Cu3O7–x powder by oxalate coprecipitation from nearly saturated solutions of the metal acetates and a 2‐propanol solution of oxalic acid was developed. The coprecipitation was complete within 5 min in an ice bath at 0–2°C. The final stoichiometry was Y:Ba:Cu...
