Ma. Camblor et al., SPONTANEOUS NUCLEATION AND GROWTH OF PURE SILICA ZEOLITE-BETA FREE OFCONNECTIVITY DEFECTS, Chemical communications, (20), 1996, pp. 2365-2366
A microporous SiO2 material isomorphous to zeolite-beta showing an enh
anced crystallinity and thermal stability due to the absence of connec
tivity defects, spontaneously nucleates and grows in a hydrothermal sy
stem containing tetraethylammonium and fluoride ions at near neutral p
