Abstract : The excellent mechanical properties and outstanding water corrosion resistance of Y-Si-Al-O-N glasses indicate that they are attractive candidate materials for forming into high performance glass fibers. Fibers of glasses containing, respectively,3.2 and 6.6 wt% N were drawn freehand in air, and from glass rods in N2. Continuous fibers (100-m long) of the former glass were melt-drawn in N2 while being wound in air outside of the glass-melting furnace. Some fibers had diameters as small as 10 um, and characterization data show that the fibers retain all of the desirable properties of the bulk glass.
