What is it about?
In oxynitride glasses, oxygen atoms are partially replaced by N to provide extra cross-linking in silicate or aluminosilicate glass networks along with modifying cations such as Li, Mg, Ca, Ba, Sr or Y and rare earth lanthanides (Ln). This results in higher glass transition temperature, elastic modulus, hardness and viscosity compared with their oxide glass counterparts.

Why is it important?
Oxynitride glasses are a group of speciality glasses with superior properties to their oxide glass counterparts, one of a range of “new” glasses with novel functions that are being developed for potential technological applications.
Perspectives
Potential applications of oxynitride glasses include use as passive coatings on electronic substrates, high-speed hard disk drive substrates. There may be possibilities of developing oxynitride bioglasses with improved strength and elastic modulus. Transparent oxynitride glasses may provide improved ballistic resistance for transparent armor materials. There is also potential for oxynitride glasses as host materials for LED phosphors.
