Slip casting and ceramic injection moulding are two techniques used in industry to produce advanced ceramics, which are ceramic parts with a good net shape, high complexity and of high strength. When slip or paste formulations are made up for use in these two shape forming techniques, it is often the binder that gives the formulation the flow characteristics and strength to be shaped and removed from the mould successfully with little or no defects. Water based binders are becoming more prominent in industry in recent times than traditional oil or wax based binders. They have a number of advantages including their low toxicity, easy and quick removal and good flow properties. Latex is a relatively new water based binder which has been used in a number of ceramic shape forming techniques in industry including gel casting and tape casting. Using a novel formulation of latex as a binder, which increases in viscosity following neutralisation and heat treatment, this thesis attempts to use this binder to form advanced ceramic parts using ceramic injection moulding and slip casting. Adaptations were made to latex formulations, ceramic mix formulations, and the choice of additives, and heating sequences in order to optimise the ceramic part production. It was shown that such binders, when mixed with ceramic, are able to form ceramic parts of reasonable quality and strength using ceramic injection moulding and gel casting. It is also thought that such binders can be further adapted to suit other shape forming techniques such as tape casting.
