Preparation of MgAl2O4 Nanopowder by Homogeneous Precipitation Method

Abstract:

Article Preview

MgAl2O4 nanopowder is synthesized by homogeneous precipitation method, using MgCl2,AlCl3 and ammonium bicarbonate as starting materials. The influences of the concentration of metallic salt solution, pH value and type and concentration of surface-active agents on agglomeration have been discussed. The results show that with addition of suitable amount of anion surface-activeagent, MgAl2O4 nanopowder with particle size of less than 12nm and secondary particle diameter of less than 170nm can be obtained by heated precursor at 850°C for 1h.
