説明
Al2O3-ZrO2 composite precursor was synthesized by introducing ammonia into a liquid mixture of ZrO2 sol and Al(NO3)3 aqueous solution. Precipitation of bayerite suggested a degradation in the dispersion of ZrO2 nanoparticles in the Al2O3 matrix during heat treatment. In order to avoid the formation of bayerite, it was preferred to produce a precipitation with a diluted NH3 water solution with NH3+N2 gas by controlling the hydration temperature and the NH3-adding methods. After suitable calcination and hot pressing, we successfully synthesized a uniform Al2O3-ZrO2 microstructure in which tetragonal zirconia particles of 30nm were finely dispersed within the alumina grains.
