Abstract
The aim of this work is to study the influence of calcium phosphate on sanitaryware suspension viscoelasticity. The specific interest was given to use of waste calcium phosphate instead of feldspar in a sanitaryware slip: the goal is to set up a new formulation of raw materials with the same rheological properties and related casting parameters of the traditional one. Above all, two suspensions parameters were studied: the calcium phosphate concentration and the aging effects. The most appropriate calcium phosphate concentration and aging time were found.
