| Abstract Scope |
The behavior of a polyvinyl pyrrolidone based binder system was evaluated for dry pressing of lead-zirconate-titanate bulk ceramics. Three polyvinyl pyrollidones, Kollidon 25, Kollidon 90F, and Kollidon VA64, were blended with up to 50 wt% polyethylene glycol and 20 wt% glycerin. The glass transition temperature, thermal decomposition behavior, and compaction behavior and green mechanical properties when mixed with PZT were evaluated. A binder system with orders-of-magnitude improvement in compaction behavior and green mechanical properties was developed. Optimization of the binder system using statistical design of experiments will be discussed.
