Synthesis of a novel Yellow Tb-doped ZrSiO4 Pigment by Suspension Spray Drying

The colloidal processing route has several advantages over other processing methods for obtaining dense and homogeneous microstructures. The aim of the present work is to obtain a yellow pigment based on the substitutional doping of Tb4O7 into the ZrSiO4 structure using a colloidal route and to investigate its feasibility as a coloring agent for fast double firing tiles.
