This study evaluated the possibility of producing innovative glass-ceramic foams from zeolite-
poor rock (Tokaj, Hungary) using alkali-activation and reactive sintering techniques. The
composition and morphology of the samples were studied using X-ray diffraction, X-ray
fluorescence, scanning electron microscope, and computed tomography techniques. The
influence of various sintering temperatures on glass-ceramic foams was examined. It has
been observed that zeolite-poor rock has a self-foaming capability. The heat treatment …
