X-ray Diffraction Analysis on Effect of Time Reaction and Alkali Concentration in Merlinoite

Abstract

This research objectives is to determine the effect of time reaction and alkali concentration on the synthesis of merlinoite. The synthesis of merlinoite was performed by hydrothermal method with variation of reaction time in 8, 12, 24 hours and various concentration at 1, 3, 5M. The quantitative X-Ray Diffraction (QXRD) was employed on product using Le Bail refinement method. Characterization XRD shows the highest crystallinity of the product was obtained at 3M of alkali concentration in 8 hours reaction time. The refinement result revealed three other phases such as quartz, mullite, and tobermorite.
