Procedure for obtaining ZnO particles with acicular morphology.

摘要

Procedure for obtaining particles with acicular morphology ZnO. The present invention utilizes the controlled precipitation method for ZnO particles with acicular morphology. Through control of the parameters of formation of intermediate precursors of zinc compounds and the evolution of these intermediate precursors by washing with distilled water of the colloidal suspension obtained zinc hydroxide. Distillation 100-150 ° C of an aqueous suspension of zinc hydroxide causes the formation of zinc oxide particles with acicular morphology. The particle size varies with the conditions for obtaining, with the standard size of 0.5 {mi} m in diameter and 8/5 {mi} m. Process efficiency is over 90%.
