Mechanochemical synthesis of alumina nanoparticles
Abstract: Nano- size alumina particles have been synthesized by mechanical activation of a dry powder mixture of AlCl3 and CaO. Mechanical milling of the above raw materials with the conditions adopted in this study resulted in the formation of a mixture consisting of crystalline CaO and amorphous aluminum chlorides phases. There was no sign of chemical reaction occurring during milling stag...
متن کاملKinetics of Fe2O3-Al reaction prior to mechanochemical synthesis of Fe3Al-Al2O3 nanocomposite powder using thermal analysis
The effect of ball milling on kinetics of the thermite reaction of 3Fe2O3 + 8Al powder mixture to synthesizeFe3Al-Al2O3 nanocomposite was investigated using differential thermal analysis. A model-free methodwas applied to the non-isothermal differential calorimetry (DSC) data to evaluate the reaction kineticsaccording to the Starink method. The activation energy of the thermit...
متن کاملsynthesis and characterization of vanadium boride nanostructure powder via milling and mechanochemical reduction process
in this article vanadium boride nanopowder was synthesized by mechanochemical reduction method in a high-energy ball mill. the synthesized powders were studied by x-ray diffraction (xrd), scanning electron microscopy (sem), xray map and transmission electron microscopy (tem). according to x-ray diffraction the product predominantly consists of vb phases after 100 min milling without further hea...
متن کاملEfficient mechanochemical synthesis of regioselective persubstituted cyclodextrins
A number of per-6-substituted cyclodextrin derivative syntheses have been effectively carried out in a planetary ball mill under solvent-free conditions. The preparation of Bridion® and important per-6-amino/thiocyclodextrin intermediates without polar aprotic solvents, a source of byproducts and persistent impurities, could be performed. Isolation and purification processes could also be simpl...
متن کاملExpeditious, mechanochemical synthesis of BODIPY dyes
BODIPY dyes have been synthesized under solvent-free or essentially solvent-free conditions, within about 5 minutes in an open-to-air setup by using a pestle and mortar, with yields that are comparable to those obtained via traditional routes that typically require reaction times of several hours to days.
