Abstract

Different sol-gel methods for the preparation of ZrO2 were investigated. Depending on the chemical composition of the initial solutions, various results such as gel-precipitation, the formation of stable sols or amorphous gels were obtained. Sols prepared by different methods are composed of different structural units and exhibit quite different rheological behaviour such as shear thickening, Newtonian flow, shear thinning and thixotropic flow. By variation of the chemical composition of the sol, an optimized rheological behaviour can be achieved for a given purpose.
