Glass-ceramic foams produced from zeolite-poor rock (Tokaj)

Abstract 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 morphology samples were studied X-ray diffraction, fluorescence, scanning electron microscope, computed tomography influence various temperatures on was examined. It has been observed that a self-foaming capability. heat treatment temperature affects pore size distribution as well technical characteristics obtained samples. resulting possess moderate thermal conductivity ranging 0.11 to 0.17 W mK −1 good compressive strength (1.5–4.4 MPa). produced might be utilized for insulation, which would have both economic environmental advantages.
