Abstract
Procédé perfectionné pour durcir en surface un support de matière minérale par diffusion à chaud d'une matière minérale différente. Selon l'invention, le chauffage provoquant la diffusion de la matière dans le support s'effectue dans une atmosphère de vapeurs de métal alcalin. Dans les vapeurs de métal alcalin, on évite toute oxydation du support.
