use | used to make indicators, catalysts and organic synthesis intermediates. |
application | cobalt oxalate (CoC2O4) as the main raw material for preparing co powder can be used to make hard alloy, and its structure and properties have great influence on co powder. |
preparation | ammonium oxalate is used as precipitant. when the reaction temperature is 50 ℃, ammonium oxalate solid is quickly added to cobalt sulfate solution (solid-liquid feeding method) to obtain ultrafine cobalt oxalate with uniform particle size and 1.1 μm particle size. However, ammonium oxalate solution is added to cobalt sulfate solution (liquid-liquid feeding method), the yield of cobalt oxalate can be as high as 99.6%. |
