Abstract
The life of ceramic SPF dies can be enhanced significantly by plasma spray application of a cordierite glaze on the forming surface. The preferred glaze has a coefficient of thermal expansion close to or matching with the ceramic of the die, and, typically, is a 2•2•5 MAS system including 2-10 mol % TiO (or above 8 wt %).
