ABSTRACT:
The invention provides partially stabilised zirconia and alumina based electro-static dissipative or ESD ceramic compositions. The proposed ceramic compositions include specific amounts of dopants comprising one or more metal oxides selected from iron oxide, chromium oxide and titanium oxide. The proposed ESD ceramic materials are made into useful industrial products by injection moulding and sintering technology. A novel binder system may optionally be used to make injection mouldable feedstock. Useful products produced by the invention include, for example, ESD ceramic tweezers tips, ESD ceramic dispensing needles, ESD ceramic scissors and blades and ESD ceramic wire bonding capillaries which retain their ESD properties at relatively low temperatures, for example, service temperatures from 25 to 500° C.
