N2 - Glasses have been prepared in the Si ‐Y‐Al O‐N system by melting mixtures of silica, alumina, yttria, and silicon nitride. One particular glass containing 17 equiv% N has been investigated to Observe the crystallization at temperatures in the range 1050o‐1300oC. The major crystalline phase observed is Y2Si2O7, existing as the α form below 1200oC and the β form above this temperature. Properties of the glass‐ceramic, including thermal expansion coefficient, hardness, electrical resistivity, and creep have been assessed.
