Abstract: 

HYDROTHERMALLY SYNTHESIS OF CUO/ZNO/AL2O3 NANOPOWDER SUCCESSFULLY CARRIED OUT. THE EFFECT OF CRYSTALLIZATION TIME ON PRODUCT PROPERTIES WAS OBSERVED AND 6 H REACTION TIME, BASED ON POWDER XRD ANALYSIS AND FESEM IMAGING, WAS SELECTED AS THE BEST CRYSTALLIZATION DURATION IN RANGE OF 3-12 H. NANO POWDERS WERE CHARACTERIZED USING XRD, FESEM, EDX MAPPING, FTIR, TG AND BET TECHNIQUES. THE XRD PATTERNS CONFIRMED CRYSTALLINE METAL OXIDE FORMATION. GOOD CRYSTALLINITY OF SAMPLES WAS OBSERVED WITH FESEM IMAGE WHICH CONFIRMED XRD ANALYSIS RESULTS. SCHERRER EQUATION CALCULATIONS SHOWED AVERAGE CRYSTALLITE SIZE OF 20 NM FOR PRODUCTS AND FESEM IMAGES SHOWED NANO SCALE PARTICLES. THE BES SURFACE AREA MEASUREMENT SHOWED ACCEPTABLE VALUES FOR SYNTHESIZED CZA SAMPLES. FTIR SPECTROSCOPY CONFIRMED METAL OXIDES FORMATION DURING HYDROTHERMAL AND CALCINATION PROCESS. TGA RESULTS ILLUSTRATED HIGH THERMAL STABILITY OF THE SYNTHESIZED NANO POWDERS.
