Product Description
Cobalt oxalate powder
Cobalt oxalate (CoC2O4), as the main raw material for preparing Co powder, can be used to manufacture hard alloys, and its structure and properties have a significant impact on Co powder. The liquid phase precipitation method is a simple, low-cost, and excellent method for preparing powder materials. However, the preparation process conditions of liquid-phase precipitation method have a significant impact on the performance of the powder. For the preparation of cobalt oxalate, there have been no reports on the effects of feeding methods, reaction temperature, and reactant concentration on the particle size, morphology, and yield of cobalt oxalate powder. The study of particle size and morphology is of great significance for expanding the application range of cobalt oxalate, and how to improve the yield has practical economic value.
When cobalt oxalate decomposes, the strength of the oxidation atmosphere and temperature have a significant impact on the form of cobalt oxide produced. There are three forms of cobalt oxide, with grades of CoO78.65%, Co2O371.03%, and Co3O473.43%, respectively. According to thermodynamic calculations, when CoO is oxidized in air at 400-900 ºC or oxygen at 300-400 ºC, Co3O4 can be generated, but only at low temperatures (less than 200 ºC) or high temperatures (oxygen pressure exceeding 1.01 × Only at 107Pa can Co2O3 be generated. Therefore, in order to obtain Co3O4 products, the reaction can be controlled in air at 400-900 ºC.
