Esse artigo apresenta a análise termodinâmica do ponto de vista do processamento cerâmico para a obtenção de niobatos de potássio. A análise realizada indicou as condições de pH em que seria possível produzir insumos cerâmicos fotoluminescentes por rotas de precipitação química. Para tanto foram consideradas as presenças dos elementos químicos Ca, La, K, Nb e Eu em meio aquoso à temperatura ambiente, que foram estudados considerando os parâmetros potencial e a solubilidade. 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
