摘要
以草酸铜在氩气中的热重分析为依据,利用X射线衍射、扫描电镜和高分辨透射电镜对草酸铜在氩气中热分解的最终产物进行分析。结果表明:草酸铜在氩气中以3℃/min升到330℃并保温20 min获得铜粉,该铜粉为10 nm左右的球形颗粒。
The thermal decomposition of CUC204 in the argon gas was built based on TG analysis. The thermal decomposition products of CUC204 in the argon gas were characterized by X-ray diffraction, scanning electron microscope and transmission electron microscope. The results show that copper powder can be obtained by thermal decomposition of CUC204 from room temperature to 330 ~C under the rate of 3 ℃/min and at 330 ℃ for 20 min in argon gas. The particle size of the copper powder is about 10 nm.
