摘　　要：纤维状镍粉可通过纤维状草酸氨镍晶体热解制得,本文研究了不同条件下热分解纤维状镍盐制备出的纤维状镍粉形貌和性质,XRD、TG、显微镜照片、比表面积测定等结果表明:选取纤维状好的复杂镍盐,在400～440℃温度之间,较弱还原气氛下热解30min制得的金属镍粉具有良好的纤维状和分散性。Fibrous nickel powder can be made through thermolysis of the fibrous complex nickel oxalate crys- tal. This paper studies the different conditions thermal decomposition fibrous nickel salt preparation the fibrous nick- el powder morphology and properties,XRD,TG, microscope photos and specific surface area measurement. The re- sult show that： the better fibrous complex nickel salt in the temperature between d00 - 440~C, weak reduction at- mosphere pyrolysis 30 minutes system of metal nickel powder has good fibrous and dispersion.
