Abstract

Oxynitride glass ceramics are an emerging class of materials which offer improved refractoriness and mechanical properties compared with conventional oxide glass ceramics, and easier fabrication and more controlled microstructures compared with current crystalline nitride and oxynitride ceramics. Since their original observation in the grain-boundaries of crystalline nitrogen ceramics, they have been prepared pure from bulk oxynitride glasses, and their physical, chemical and ceramic properties evaluated. A particularly important aspect of this development has been the increasing numbers of new phases reported; this offers more choice as regards materials selection for specific applications. The present paper focuses on the yttrium sialon system, and describes recent work carried out on two of the five-component phases in this system.
