COBALT(II) OXALATE Usage And Synthesis

Uses

Used to manufacture indicators, catalysts, and intermediates in organic synthesis.

Application

Cobalt oxalate (CoC2O4) is the main raw material for preparing Co powder and can be used to manufacture cemented carbide. Its structure and properties have a great influence on Co powder.

Chemical Properties

Rose red powder

Flammability and Explosibility

Not classified

Synthesis

Using ammonium oxalate as the precipitating agent, when the reaction temperature was 50 ??, the ammonium oxalate solid was rapidly added into the cobalt sulfate solution (solid-liquid dosing method), the ultrafine cobalt oxalate with uniform particle size and 1.1 ??m particle size could be obtained; and using the ammonium oxalate solution to be added into the cobalt sulfate solution (liquid-liquid dosing method), the yield of cobalt oxalate could be as high as 99.6%.
