From a KZn(NO 3 ) 3 glass melt it is possible to prepare, at 180°C, ZnO particles having a hemispherical morphology with an average diameter of 300 pm. Careful microscopic examinations and the behavior of the particles during annealing are presented. The addition of 1 wt% Co in the glass melt leads to the formation of ZnO spherules.
