LOW TEMPERATURE MOLTEN SALT SYNTHESIS OF NANO CRYSTALLINE MgAl2O4 POWDER
Abstract: composition of MgO and nano boehmite. The reactant and potassium chloride, as the reaction media, were fired at800-1000 °C at different dwell times (0.5-5 h) in the ambient atmosphere. After washing and filtration, the spinel nanopowder was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) techniques. It was demonstrated tha...
متن کاملTITANIUM ALUMINIDES SYNTHESIS BY ALUMINO-CALCIOTHERMIC REDUCTION OF TiO2
Abstract: Production of titanium aluminides in TiO2-Al-Ca system has been investigated. For this purpose, different compositions of raw materials were studied in a special reaction vessel. In a special case, the non-completed reaction of TiO2 with Al and Ca resulted in the production of granulates of titanium aluminides especially Ti3Al and other Ti – Al phases as the metallic product and C...
متن کاملElectrochemical Synthesis of Magnesium Hexaboride by Molten Salt Technique
The present work reports electrochemical synthesis of MgB6 from molten salts using the precursor consists of LiF-B2O3-MgCl2. An attempt has been made to synthesize metastable phase MgB6 crystal by electrolysis method. DTA/TGA studies were made to determine the eutectic point of the melt and it was found to be around 900°C. The electrolysis was performed at 900°C under argon atmosphere, at curre...
متن کاملMolten Salt Synthesis of Calcium Hydroxyapatite Whiskers
Calcium hydroxyapatite (HA) whiskers and crystals were produced by the route of molten salt synthesis. The effects on whisker morphology of chosen flux, flux-to-HA ratio, synthesis temperature, and reaction time were investigated. The thermal stabilities of the produced whiskers were tested at 1300°C in an air atmosphere. A tentative X-ray diffraction pattern was proposed for the HA whiskers. M...
