Abstract

The study of the binder removal processes for injection moulded ceramic composite compacts was studied with the aid of a thermogravimetric analyser. It has been observed that a number of factors, such as the heating rate, the heating environment and the heating profile have an effect on the rate of binder removal. The matrix of the composite was alumina and the reinforcement was silicon carbide whiskers. It was confirmed that the presence of silicon carbide whiskers in the injection moulded compacts provided additional oxygen diffusion paths to enhance oxidative degradation. It was also found that the heating profile used for binder removal had a strong influence on the formation of internal cracks in the moulded components. © 1997 Elsevier Science Ltd.
