K. Karim et al., SYNTHESIS AND CHARACTERIZATION OF HEXAGONAL-Y (EMT) AND CUBIC-Y (FAU)- EFFECT OF TEMPLATE AND FLUORIDE IONS ON THE ZEOLITE PRODUCT, Microporous materials, 3(6), 1995, pp. 695-698
Siliceous cubic Y (FAU) and hexagonal Y (EMT) materials are synthesise
d and characterised. The effect of varying the amount of template (cro
wn ethers) and of adding fluoride ions to the synthesis gel on the mor
phology and crystal size of product crystals is discussed. Smaller, mo
re uniform, crystals were obtained when fluoride ions were added to th
e synthesis mixtures.
