Research on the Thermal Decomposition of CoC_2O_4·2H_2O in the Argon Gas AITranslate
Abstract AITranslate
Analysis is made on the thermal decomposition of CoC2O4 · 2H2O in the argon gas by TG-DSC and laser granulometer. The results showed that the thermal decomposition was done in two stages. First, the crystal water in CoC2O4 · 2H2O was lost at 150～275 ℃. Then,CoC2O4 was pyrolyzed into cobalt pow- der at 300～450℃. At 328.0～347.7℃ ,the biggest particle size change is found in the product,while at 347.7～500℃ ,the product particle size change is less. And between room temperature and 226.2 ℃ ,and at 226.2～328.0℃ ,the particle size change is not obvious. Therefore, the thermal decomposition condition of CoC2O4 · 2H2O in the argon gas can be controlled in stages in order to prepare cobalt powder of different particle sizes.
