中文摘要: 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︰1、25︰1和50︰1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0.2~2.5 μm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︰1, 25︰1, and 50︰1, respectively. Microstructures are mixture of 50~100 nm nanowires and 50~200 nm particles as molar ratio of Si/Ti is 20︰1, mixture of 30-50 nm nanowires and 100-250 nm particles as molar ratio of Si/Ti is 25︰1, and 0.2-2.5 μm particles as molar ratio of Si/Ti is 50︰1, respectively.
