The Wetting Behavior of Yttria-Alumina-Silica Additives for Pressureless Sintering of Silicon Nitride.

Abstract

The aims of this study were to observe and measure the wetting behavior of liquid yttria-alumina-silica mixtures when in contact with silicon nitride at high temperature and in an environment of one atmosphere of nitrogen. Preliminary indications suggest that over a wide range of yttrium contents, the wettability range is small and that the compositions are reactive to the substrate even though they do not wet readily. A much larger experimental data base is necessary, however, over a wider range of experimental conditions to understand the wetting characteristics and reaction behavior in this complex system.
