“…Other raw materials such as high silica bauxites, halloysites, and montmorillonites are also used for synthesis of zeolites (Aiello et al, 1984). Synthesis of zeolite A from other sources has also been reported (Breck, 1974;Fernandez et al, 1974; Drag et al, 1985; Van Erp et al, 1987;Szostak R., 1989;and Hu and Lee, 1990).…”

Optimization studies are carried out for the synthesis of zeolite A by a hydrothermal method using calcined diatomite. Fractional factorial design of experiments along with path of steepest ascent is used to optimize the composition and process parameters. A surface methodology technique is used to obtain the optimum value of the process parameters to maximize the percentage crystallinity of zeolite. It is found that SÍO2/AI2O3 molar ratio of 1.31, Na20/Si02 molar ratio of 3.61, and temperature of hydrogel formation of 35.7 °C give maximum crystallinity of 92% at the crystallization temperature of 110 °C and reaction time of 51 h. * To whom correspondence should be addressed. f Materials Science Programme.

“…Zeolite like materials are generally synthesized from an aqueous system under hydrothermal conditions. During the last decade, some reports [1][2][3] have mentioned the influence of the organic or mixed organic-water solvents on the preparation of the microporous compounds. A wide variety of alcohols (mainly glycols) has been tested for the synthesis of zeolites and also phosphate-based compounds.…”
