摘要
The invention relates to a process for preparing pieces of solid electrolyte based on stabilized zircon having an improved conductivity due to the addition of Al.sub.2 O.sub.3. According to the process, an alcoholic solution is prepared of a salt of zirconium, a salt of a metal stabilizing zircon such as yttrium and a salt of aluminium; from this solution is formed a coprecipitate of hydroxide of zirconium, hydroxide of said metal and hydroxide of aluminium; the precipitate is washed by means of a hydrophilic solvent to eliminate the traces of water, then is dried and calcined in air; a piece of solid electrolyte is then formed by compression and sintering from the powder obtained.P PThe invention is applicable to the production of solid electrolytes for cell for electrolysis of water vapor or for fuel cell.
