A structural model for low silica content calcium aluminosilicate glasses

A new structural model is proposed to explain the maximum in T g observed in the 5-75 mol% SiO 2 content range of calcium aluminosilicate glasses with low silica contents. A correlation between T g and the concentration of O 2 - determined by electron spin resonance is presented. The experimental results are explained by a structural model based on the calcium aluminosilicate liquidus phase diagram
