Abstract
Procédé de fabrication de membranes minérales perméables se caractérisant en ce que l'on dépose sur un substrat poreux perméable une couche mince d'un gel d'hydroxyde au moins d'aluminium peptisé, on sèche la membrane ainsi obtenue, puis on la soumet à une cuisson à une température comprise entre 500 et 1100 degrés C. Application des membranes obtenues à la séparation isotopique de gaz, à la filtration et à l'ultrafiltration.
