Abstract

Abstract

he Nanomic composite oxied power of(W,Ni,Fe)system is made in a ultrasionic spray heat-transfer device using rapid mixig method of alkalinous solution of H₂WO₄,NiCl₂ and FeCl₂ solution.The phase composition of the composite oxide power and its relation to the flux used are studied by means of X-ray diffraction and(XRD)TEM analysis.The shape characteristics of power particle and the particle range are studied as well.The results show that homogenous composition of composite oxide power can be made by the methods of rapid mixing of the above two solutions and ultrasonic spray heat-transfer methods.When the self-made oxide flux is used,the phase composition of composite oxide power is WO₃,NiO.The powder particle range is 15~50nm and the particle shape is near to sphere.
