Development Of High Cte Glass-Ceramics For Sealing

High CTE glass-ceramics are required for sealing applications. The crystallisation and nucleation behaviour for two candidate lithium silicate based glasses, AZS2 and AS13, have been optimised for high CTE values using the method developed by Marotta et al. The ideal nucleation time and temperature was determined as 750cC for 120m for AZS2. This gave the crystalline phases cristobalite, tridymite and a Li2ZnSiO4, yielding a glass ceramic of CTE 18-18.5 x 10-6K-1.
