Thermal and structural role of additives in P2O5-ZnO-Sb2O3 glass for low expansion sealing materials
A glass based on the P 2 O 5 -ZnO-Sb 2 O 3 ternary system was modified with various additives, such as RO (R=Ca, Ba and Mn), B 2 O 3 and V 2 O 5 , for low temperature and low expansion sealing materials. The glass transition temperature (T g ) and coefficient of thermal expansion (CTE) were monitore...
