Notes:
Homogenization of Y2O3 as a sintering additive in AlN green compact has been achieved by chemisorption of Y(NO3)3 on AlN particles in isopropanol suspension. Substantial adsorption of Y(NO3)3 equivalent to a Y2O3 content up to a maximum of 1.4 wt% of AlN has been observed. Electrokinetic mobility measurements of the coated particles and the adsorption studies show that the adsorption takes place in isopropanol suspension. SEM shows a good homogeneous distribution of Y2O3 in the green ceramic compacts, and no trace of secondary crystallization has been observed.
