摘要
本文用比色法,X射线粉末衍射法及原子吸收光谱法对以“NaNo_3+C(石墨)”为主要组元的铸造铝合金精炼剂在铝硅合金液中反应的气相产物、非气相产物及合金中的微量元素进行定量和半定量分析,并结合热力学验证,较系统地研究了该类精炼剂在铝合金液中的反应原理。
By using colorimetry, X-ray powder diffractometer and atom abeerption spectrometer analyzing (?)tltatively and semiquatitatively the gaseous, (?)-ga(?)eous products and the microelemests in Al-Si alloys after the reseting of Al alloy degasser 'NaNO_3+C(graphite)'in the alloy melt,together with thermodyuamic and kinetics analysis, the reaction alloy melt has been systematically studied.
