This work presents a thermodynamic analysis from ceramic processing point of view to obtain photoluminescent potassium niobate ceramic. The analysis carried out indicated the conditions of pH which the route of processing by chemical precipitation would be done. Therefore, the presence of chemical elements Ca, La, K, Nb and Eu in aqueous medium was considered on potential and solubility parameters at room temperature.
