Abstract

We have studied glass formable region in the Y₂O ₃-CaO-Al₂O₃ system. An optimal composition for the amorphous phase formation was found in the pseudo-eutectic 12CaO•7Al₂O₃-CaYAlO₄ system. An amorphous bulk plate of 10 × 25 × 1.8 mm was successfully fabricated using a simple molding technique. The fabricated glass plate showed an IR absorption edge at around 5.6 μm. The crystallization of the glass sample was observed above 890°C by an X-ray diffraction (XRD) and Thermogravimetry and Differential thermal analysis (TG-DTA).
