Method to form a superconductive ceramic product and the product thus obtained and the intermediate product

摘要

Method to form a superconductive ceramic product according to which a suspension is formed of an organic solvent, an organic polymer binding agent and a superconductor- powder, being a superconductor- powder or a superconductor- precursor or a mixture of powders becoming superconductive after a thermal treatment, or a mixture of two or more of these materials, this suspension is brought into the required form, the solvent is removed from the suspension, the binding agent is removed thermally and the then obtained product undergoes a thermal treatment, characterized in that polysulphone is used as an organic binding agent and the solvent is removed from the suspension brought into form by means of extraction with a non solvent.
