SYNTHESIS PROCESS OF A CRYSTALLINE ALUMINOSILICATE ENRICHED IN SILICE, WHICH HAS THE SUPPLY STRUCTURE, FROM A NUCLEATION GEL CONTAINING SOURCES OF SILICON, ALUMINUM IOLS, ALKALINE IONS AND A WATER B) WHICH CONTAINS THE SOURCES OF SILICON, ALUMINUM, ALKALINE IONS AND WATER. THE CRYSTALS FORMED ARE CALCINATED, EXCHANGED IN THE PROTON AND SUBJECTED TO A HYDROTHERMAL TREATMENT AND THEN TO A TREATMENT BY A STRONG MINERAL ACID.
