Effect of Inflow Rate of Raw Material Solution on the Fabrication of Nano-Sized Cobalt Oxide Powder by Spray Pyrolysis Process

Autor: Dong Hee Kim, Jae Keun Yu

Publikováno v: Korean Journal of Materials Research. 26:662-669

In order to identify changes in the nature of the particles due to changes in the inflow rate of the raw material solution, the present study was intended to prepare nano-sized cobalt oxide (Co3O4) powder with an average particle size of 50 nm or les
