Study of precursor system and controlling conditions of alumina nanometer powders prepared by hydrolysis of alkoxide |

| Abstract: | The precursor system in preparation of alumina nanometer powders was studied by taking the feasibility of production into account. The controlling conditions which influence the alumina particle size, shape and distribution were investigated. The results show that Al(OPr i) 3 selected as precursor, toluene as solvent are the optimum conditions. The ratio Al(OPr i) 3/H 2O in mole, category of additive and aging time of solutions are the efficient factors to control the particle size and shape by two step hydrolysis. |
