Effect of composition and sintering temperature on thermal properties of zeolite-alumina composite materials

This research work provides a technical description of the utilization of natural zeolites in the synthesis of ceramic composite material using mechanical milling and reactive sintering technique. Two commercially available minerals (Natural zeolite from Mad in Tokaj region and MOTIM Al2O3) were used as starting raw materials, A comprehensive analysis has been conducted for the detailed characterization of raw materials as well as produced products, the analysis combines the mineralogical examination using X-ray diffraction (XRD) together with chemical constituent determination by (XRF) and thermoanalytical studies using (TG/DTA), heating electron microscope and thermal conductivity analyzer to determine the influence of sintering temperatures on the thermal properties of the produced zeolite-alumina composite materials. Based on the results obtained from XRD, XRF and TG/DTA, the authors have found a great connection between the composition, firing temperature and thermal properties of the produced ceramic samples.
