Abstract

Calcium aluminate optical glasses were prepared by air quenching, using Al2O3 (A), CaCO3 (C), Na2CO3 (N), BaO (B) and SrCO3 (S) as preparatory powders. The glass-forming ability and stability were determined using differential thermal analysis (DTA). The CANS composition showed the best glass-forming ability, while the CAN composition showed the worst one. The CAB, CAS and CA compositions showed small isolated crystals, while the CAS and CANB showed partial crystallization with a slightly large portion. The CANB glass was determined to be the most stable glass among the glasses prepared.
