Abstract

Zinc oxide nanopowders have been successfully prepared via microwave hydrothermal process. The reaction were carried out in hydrothermal conditions under a pressure of up to 4 MPa using a microwave reactor. The application of microwave energy for the processing of ceramics has become an attractive area of research and innovation recently. Zinc oxide was prepared by the decomposition of different zinc saltz in an aqueous solution under alkaline conditions or by the addition of TEA ( triethanolamine) and urea. The effects of reaction temperature, synthesis time and synthesis conditions on the particulate properties such as the particles morphology and grain size are disscussed. Zinc oxide particles of various shapes and sizes were produced.

Keywords : Nanopowders, Zinc Oxide, Hydrothermal method, Chemical synthesis.
