Effect of Carbon Content in Cobalt Tetroxide on the Quality of Ultrafine Cobalt Powder AITranslate
Abstract AITranslate
Industrial cobalt carbonate was used as raw material and calcined to form cobalt tetroxide with different carbon contents in a muffle furnace.Then the cobalt oxide was reduced to cobalt powder through a single-tube test furnace.The powders were characterized by Fisher particle size analyzer, laser particle size analyzer, oxygen content meter, carbon and sulfur meter, scanning electron microscope and other equipments.The results show that cobalt tetroxide with carbon content of 0.033%~0.195% can be obtained by adjusting the calcination process.As the carbon content of cobalt tetroxide increases, the particle size of cobalt powder gradually increases.When the carbon content of cobalt tetroxide is 0.033%,Fsss particle size of the cobalt powder is 0.94 μm, and when the carbon content of cobalt tetroxide is 0.195%,Fsss particle size of the cobalt powder is 1.13 μm, increased by 20%.With the increase of carbon content of cobalt tetroxide, the porosity of cobalt powder slightly increases, the bulk density has an increasing trend, the oxygen content is small, and the carbon content has no significant fluctuation.The gas flow classification process of cobalt tetroxide can reduce the particle size of the reduced cobalt powder.The surface of the cobalt powder reduced from high-carbon cobalt tetroxide is smoother and the sphericity is slightly worse.
