Summary

The oxygen present in α-Si3N4 powder greatly affects its sintering. The total oxygen content in Si3N4 as determined by combustive decomposition has been discussed previously. In this study, oxygen content in the surface layers of various α-Si3N4 powders decomposed by HF was determined. The surface properties of the wet-ground product were found to differ from those of the dry-ground product. This was confirmed by photoelectric spectro-photometry (XPS) and transmission electron microscopy (TEM). The effects of the surface properties of α-Si3N4 dispersed in water at various pH on the stability and viscosity of slurry were also investigated.
