Abstract

Chlorine-containing CaO-Al<SUB>2</SUB>O<SUB>3</SUB>-SiO<SUB>2</SUB> glasses were prepared. TG-DTA (thermogravimetry-differential thermal analysis) and TG-MS(thermogravimetry-mass spectrometric analysis) results showed that HCl gas was liberated from the glass above the temperature near glass transition. It was confirmed that chlorine in the glass reacts with water in the glass and in the atmosphere. It was considered that chlorine is replaced with oxygen in the atmosphere at the higher temperature. Glass transition temperature was found to decrease with introducing chlorine into the glass, suggesting that the glass structure was weakened by chlorine ions. The surface of glass containing chlorine has high reactivity with water and carbon dioxide in atmosphere.
