Multianion Glasses,d in our laboratory. Examples of the preparation of melt solidified oxynitride, oxyfluoronitride, and oxycarbide glasses are presented. Data on the thermal stability, crystallization behavior, and microscopic characterization of selected glass systems and the effects of anion substitution on glass properties are discussed.

Non-destructive Evaluation of Ceramic Surfaces and Sub-surfaces,roscope is discussed and its application is described in general and with specific reference to engineering ceramics. Experiments performed using a prototype microscope on a silicon nitride sample, that contained an open crack in the surface, resolved both this feature and sub-surface lateral cracks that were not evident by surface inspection.

Preparation of Sialon Ceramics from Low Cost Raw Materials,ible. The powders can be sintered to high densities in either a protective powder bed or under a protective gas atmosphere without the use of additives. Some preliminary properties have been determined and suggest that the sialons derived from clay and coal have properties superior to those of many conventional refractories.
