An in situ energy-dispersive x-ray diffraction study of the hydrothermal crystallization of zeolite A. 1. Influence of reaction conditions and transformation into sodalite
Article Abstract:
The hydrothermal crystallization of sodium zeolite A from amorphous aluminosilsicate gels at 80-120 degree Celsius is investigated via a time-resolved in situ energy-dispersive X-ray diffraction. The course of crystallization reaction is analyzed by quantifying the Avarami-Erofe'ev nucleation growth curves, which indicate that choice of silica starting material affect the course of reaction, and the concentration of NaOH and temperature determine the crystallization behavior.

An in situ energy-dispersive X-ray diffraction study of the hydrothermal crystallization of zeolite A. 2. Effect of deuteration of crystallization kinetics
Article Abstract:
The crystallization of zeolite A from amorphous aluminosilicate gels at 10 degrees Celsius is examined by energy-dispersive X-ray diffraction. The effect of deuteration of reagents on the kinetics of a zeolite crystallization is described and the finings are discussed in relation to previously postulated zeolite crystallization mechanisms.
