Abstract
Formation of Zn-ferrite powder by flame-spraying technique from the ethanol solution of Zn and Fe nitrates was investigated to elucidate the effects of reaction conditions on the properties of products. The reaction was carried out by spraying the solution into a reactor heated by an electric furnace.
The formation of Zn-ferrite by the present method took place to completion at reaction temperatures higher than about 800°C. Among the reaction conditions which affect the particle size of powder produced, the concentration of spraying solution is most important and one can obtain Zn-ferrite powder finer than 0.5μ by its control.
