Hydrothermal Synthesis of Natrolite-Type Zeolite in the Natural Halloysite—Obsidian System

摘要

Zeolite (natrolite) was obtained based on natural halloysite and obsidian by the method of hydro-thermal synthesis. Synthetic natrolite was studied by the derivatographic, X-ray phase, and X-ray spectral methods. Dehydration-rehydration and cation-exchange properties were studied and the oxygen volume of the product was calculated.
