摘要
研究了氧化亚钴和四氧化三钴在惰性气氛及高温下的还原性 ,探讨了利用氮氧分析仪定量分析[1 ] 氧化亚钴含量的可行性 ,并与X射线衍射仪半定量分析[2～ 3] 结果进行了比较。结果表明利用氮氧分析仪先在较低温度下测定其中四氧化三钴含量 ,再用差减法求出氧化亚钴的量是可行的 ,其准确度高于X射线衍射仪半定量分析结果。
The reduction characterization of CoO and Co 3O 4 at high temperature in the inert atmosphere was investigated,and it was available to analyze the content of CoO by nitrogen oxygen determinator compared with that by X ray diffraction method Results showed that it was possible and available to get the content of Co 3O 4 at low temperature by nitrogen oxygen determinator and to calculate the content of CoO by subtraction. The accuracy of this method was higher than that of X ray diffraction method
