A process for the preparation of a material based on an aluminosilicate, said aluminosilicate consisting of aluminosilicate of hexagonal structure, characterized in that it comprises a single sintering step in which the sintering of a mixture of powders of precursors of said aluminosilicate, comprising aluminum hydroxide powder Al (OH) 3, by a hot-sintering technique with an SPS pulsed electric field; whereby a material based on an aluminosilicate is obtained, said aluminosilicate consisting of aluminosilicate of hexagonal structure. The aluminosilicate material prepared by said process can be used in a process for preparing a composite material consisting of an aluminosilicate matrix reinforced with metal oxide or metalloid reinforcements. |
