| Abstract: | The thermal decomposition processes of nickel oxalate in argon have been studied by TG,XRD techniques,the thermal decomposition steps of nickel oxalate are determined.The effects of the vacuum thermolysis temperature,the temperature rise rate and the pattern of nickel oxalate on nickel powders were studied.After the nickel powders are deactivated by filling with argon,the ultrafine nickel powder with oxygen content little than 0.64%,the oxidation rate little than 2% before 573 K and the particle size little... |
