  • Method for the preparation of wide-pore crystalline aluminophosphate molecular sieve
    Patent number: 5178846
    Abstract: An economical and environmentally safe method for synthesizing wide-pore aluminophosphate crystalline molecular sieves primarily involves inorganic synthesis requiring no structure-directing organic templates. In addition to aluminium and phosphate, further components selected from group IV of the periodic table of elements can be added to synthesize multi-component phosphate molecular sieves such as germano-silico-alumino-phosphate crystalline structures.
