| 摘 要： | 为研究硅/钛摩尔比对熔盐电解制备硅钛合金组分及形貌的影响,以等摩尔比的CaCl2-NaCl熔盐为电解质,通过改变电解原料中硅/钛摩尔比,在槽电压2.4 V、电解温度700℃下电解5 h获得电解产物。结果表明,当硅/钛摩尔比分别为20、25和50时,电解产物均为单质Si和TiSi2合金,微观形貌分别为50~100 nm纳米线和50~200 nm微粒混合、30~50 nm纳米线和100~250 nm微粒以及粒径0.2~2.5μm的块状颗粒。

| Abstract: | In order to investigate effects of Si/Ti molar ratios on component and microstructure of silicon-titanium alloys synthesized by molten salt electrolysis,products were obtained by changing Si/Ti molar ratios with cell voltage of 2.4 V at 700℃for 5 h.The results suggest that the products are Si and TiSi2 as Si/Ti molar ratio is 20,25,and 50 respectively.Microstructures are mixture of 50-100 nm nanowires and 50-200 nm particles as molar ratio of Si/Ti is 20,mixture of 30-50 nm nanowires and 100-250 nm particles as molar ratio of Si/Ti is 25,and 0.2-2.5μm particles as molar ratio of Si/Ti is 50,respectively. |
