Abstract
In this work the process of synthesis of ZrO2 is presented using controlled precipitation method taking as precursor the metallic salt ZrOCl2 •8H2O. The ceramic powders were characterized with different techniques to determine their chemical composition, crystalline structures, morphology and particle size. The particles showed a nanometric size (<200nm) and spheroidal shape to specific conditions of process. The synthesis process guarantees the reproduction of the method and therefore the characteristics of the obtained ceramic powders.>(<200nm) and spheroidal shape to specific conditions of process.
