LaAl12O19 hexaaluminate was prepared by reverse microemulsion method in the water/TritonX-100/n-butoanol/cyclohexane. LaMAl11O19 were prepared using transition-metal M(M=Fe,Co) to substitute Al in the hexaaluminate lattice with same method. The LaAl12O19 hexaaluminate and effects of M on phase compo...
