Abstract

Le procédé selon l'invention se distingue en ce que la réaction a lieu entre l'hydroxyde d'aluminium et le bicarbonate de sodium dans une suspension aqueuse agitée, à une température comprise entre 160 et 240 degrés C et sous une pression comprise entre 5 et 50 kg/cm**2, la température étant choisie en fonction de la longueur désirée des fibres cristallines du produit à obtenir.
