Abstract

The invention relates to a method of preparing ceramic parts and in particular beta sodium alumina parts. It consists in putting a ceramic powder in suspension in a polar solvent, depositing a layer of ceramic substance on a mandrel by electrophoresis while imparting to the mandrel a polarity which is the opposite of that of the powder, drying the layer, isostatically compressing the deposit, and removing the mandrel and sintering the part thus obtained; said solvent having, at a temperature substantially equal to ambient temperature, the following characteristics: - a viscosity of at most 2 centipoise; a boiling temperature of at least 60 DEG C; a relative dielectric constant of between 12 and 22; and a saturated vapour pressure of at most 50 millimetres of mercury. The invention can be used for preparing solid electrolytes used in sodium- sulphur electric cells.
