| Resource Title | Low-temperature synthesis of analcime from Philippine natural aluminosilicate |
| Date Issued | 7 July 2023 |
| Abstract | The potential of aluminosilicates in various applications gained traction due to their various properties and their distinct structure, shape, and size. However, the inherent impurities present in their structure limits their utility and usability. One approach to enhancing the applications of aluminosilicates is through zeolite transformation. Analcime is one of the commonly used zeolites, but while it can be naturally found, its abundance is limited. To address this challenge, the work aims to produce analcime from naturally occurring aluminosilicates via hydrothermal synthesis. Herein, hydrothermal synthesis was performed using three different recrystallization periods, 6 hours, 24 hours, and 72 hours, all using a 2:3:12 mass ratio of raw aluminosilicate, NaOH, and deionized water, respectively. The samples were characterized by X-ray diffraction, infrared spectroscopy, X-ray fluorescence, and scanning electron microscopy. In all three trials, analcime was produced. Increasing synthesis times demonstrated an improvement in the recrystallization of raw aluminosilicates to analcime, with the 72-h synthesis time showing only minimal traces of the starting aluminosilicates and with the purity of the synthesized analcime the highest. This is attributed to the longer interaction time of the alkali solution and the raw material. |
