Abstract

The influence of the synthesis conditions on the crystallization and crystal size of AlPO4-5 molecular sieve is investigated in a (TEA)2O–Al2O3–P2 O5–H2O system. The initial mixture composition and the crystallization method affect the crystallization and the crystal size of the product. Microwave heating of the synthesis mixture results in the formation of AlPO4-5 with nanometre-sized particles.
