Md. Alcala et al., A NEW INCIPIENT-WETNESS METHOD FOR THE SYNTHESIS OF CHEMICALLY STABILIZED BETA-CRISTOBALITE, Journal of the American Ceramic Society, 79(6), 1996, pp. 1681-1684
A new ''incipient-wetness'' method is proposed for the synthesis of ch
emically stabilized beta-cristobalite (CSC) that avoids the need to ha
ndle liquid phases as required by the set-gel routes proposed in the l
iterature, Stoichiometric compounds with the composition Si1-xAlxCax/2
O2 have been investigated, x = 0.07 represents the optimal composition
for obtaining an extremely well-crystallized material consisting of a
single beta-cristobalite phase, XRD, FTIR, DSC, and differential dila
tometry have been used for the physicochemical characterization of the
samples.
