De-Binding And Sintering Of Metals And Ceramics In Batch And Continuous Furnaces Using Vacuum/Controlled Atmospheres

This paper describes the de-binding processes used for powdered metals, ceramic/metal powder injection moulding, and ceramic forming. The de-binding of ceramic and metal systems involves many process variables effecting the final part quality. No matter how well a part is sintered, if it isn't properly de-bound, it will never attain a consistent high quality. A variety of de-binding process are described in partial pressures or positive pressures and these offer the producer a wide choice of environments to maximize the binder removal in the minimum time.
