CABRERA LOPEZ, John Jairo; NARVAEZ, José Luis  e  RODRIGUEZ PAEZ, Jorge Enrique. Synthesis of ZrO₂ nanometric using controlled precipitation. Rev.fac.ing.univ. Antioquia [online]. 2009, n.47, pp.20-28. ISSN 0120-6230.

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.
