Abstract
A precipitation technique is described which is used to produce high-q uality samples of superconducting YBa2Cu3O7 (T(c) = 91 K). The method makes use of two precipitation stages using hydroxide and oxalate as t he precipitants. The precipitate is in the form of a fine particulate powder, which is an intimate mixture of the three cations in their pre cipitant form, enabling efficient formation of the superconducting pha se; this is, we believe, a viable approach for circumventing the inher ent drawbacks of the well-established oxalate route.
