Nanocomposites mAl2O3–nYSZ by Impregnation Combustion Synthesis with Urea as a Fuel

Аннотация

The preparation of mAl₂O₃–nYSZ-6 and mAl₂O₃–nYSZ-5 nanocomposite powders (m + n =100 wt%, m = 0–60 wt%) by Impregnation Combustion Synthesis (ICS) with urea as a fuel was studied. Maximal combustion temperatures were measured and calculated for different modes of YSZ introduction. In ICS-produced powders, YSZ particles were found to be covered with an alumina layer.
