Significance of transport route for gaseous products during binder burnout of multilayer ceramic components

Abstract

Abstract

Binder burnout (BB) is a time consuming and critical step in multilayer (ML) ceramic processing. The BB schedule, especially for larger dimension ML ceramics, remains as a trial and error process in spite of substantial insight gained over the period. This paper brings out the importance of providing a proper transport route through which decomposition products can leave the ML structure and a practical method of achieving a faster BB cycle for large area ML actuators. By adopting this process, defect free ML actuators of larger dimensions have been fabricated.
