Rheological properties of zirconia toughened alumina powder for ceramic injection molding

Abstract

The rheological properties of feedstock are critical element to the success of the ceramic injection molding (CIM) process. The suitability of the developed feedstock can be reducing the problems that may arise during injection molding, debinding, and sintering. This study identifies suitable powder loading based on the rheological properties of materials by using a capillary rheometer machine. The feedstock used is a combination of zirconia toughened alumina powder with a binder that consists of high density polyethylene, paraffin wax, and stearic acid. Experimental results showed that all of the feedstocks are suitable for injection molding because of their pseudoplastic nature and low viscosity. However, the low power law index and low activation energy flow of the 57 vol.% powder loading make it most suitable for the CIM process.
