| Abstract: | Zr-Al organometallic compounds have been spray-dried and heated at temperatures 600 to 1400°C to prepare ZrO2-Al2O3 composite powders. The powders consist of balloon-like particles 0.5 to 2  m in diameter with homogeneously dispersed tetragonal ZrO2 grains 0.1 to 0.2 m in diameter. The tetragonal fraction of ZrO2 in the composite powders is higher than that in the powders prepared from sols of Zr(OBun)4 and AlOCH(CH3)2]3. The fraction is affected by the organofunctional group in the Zr-Al compounds.Zr(OBun)4 = Zr(OC4Hgn)4; AlOCH(CH3)2]3 = Al(OPri)3. |
