℃.电解实验所用电 解质的组成为78.07%Na3AlF6-9.5%AlF3-5.0%CaF2- 7.43%Al2O3,电解质分子比CR(电解质中NaF与AlF3的摩尔比)为2.3,初晶温度为947 ℃,电解温度为960 ℃,圆柱形阳极底部面积为2.5 cm2,电流密度为1.0 A/cm2;采用Philips8424 TW2424型X射线荧光分析(XRF)仪检测电解质和原铝中的杂质含量......
. Subsequently, they were pickled in a dilute solution of 5% HCl at 80 ℃ for 3 min and fluxed in an aqueous solution of 200 g/L ZnCl2, 100 g/L NH4Cl, 10 g/L NaF and 5 g/L NaCl at 80 ℃ for 10 min. Finally......
is the combination of high temperature chemical vapor deposition and reactive diffusion. The reactive procedures as follows[15, 16]. 1) NaF reacts with silicon powder to form volatile SiF2; 2) The gaseous......
distilled water (ddH2O) and ethanol. Finally, samples were dried in air. A sample, used as an anode, and two cathodic titanium plates were immersed into electrolyte solution containing NaF (0.138 mol......
生成的液态铝会与熔体中的NaF或KF发生置换反应,生成金属K和Na,同时,熔体中的Na+和K+在一定条件下也可能在阴极直接放电,析出金属K和Na.电解质中,金属K和Na的析出反应如下: Na+/K++ e=Na/K(熔融) (2) 或 Al(l)+3NaF/KF(在电解液中......
electrode (CE). The electrolyte composition containing different molar ratios of NaF to AlF3 was used, and the alumina contents were 0.5%, 1.5%, 2.5% and 4.5%, respectively. The cyclic voltammetry......
with water, and followed by pickling in 100-200 g/L HCl for 15 s. The specimens were rinsed again with the flowing water, then dipped in a flux bath consisting of 100 g K2ZrF6+100 g KCl+1 g NaF, and kept......
] obtained good modification effect by using Al-Sr master alloy and NaF. LIANG and CAI [16] modified the microstructure and improved the mechanical properties of ZL102 by using 0.1%-0.05% RE and 0.1%-0.15......
用瓦特性镀镍溶液.电解镍板为阳极,在铜表面预镀镍.将电镀后的试样先用清水冲洗掉镀层表面的残留电镀液,然后用丙酮作清洗液,超声清洗,烘干备用. 根据前面研究结果[13-14],选用以下试剂:分析纯SiO2(45 μm)为渗Si源,35%(质量分数);Al粉(45 μm)为还原剂,25%;Al2O3作为惰性添加剂,30%;以蛋白质(鸡蛋清)作为粘结剂,NH4Cl和NaF作为复合活化剂,10%;添加适量......
