), which is strong acid-resistance to HF. Unlike HF,the chemical stripping-off effect of the particle size of silicon powder made by aqua regia decreases obviously and the impurity phases easily expose at the grain boundaries. The loss rates of Si powder after two acids are less than 3.5%. Key words: metallurgical silicon; acid leaching; purification process; impurity phases 太阳能光伏发电产业因其取之不尽,用之不竭,清洁环保和安......

Conclusions (1) Two precipitate phases are identified in the 2297 Al-Li alloy thick plate: AlCuMnFe phase and T1 phase. For the three sections, the two precipitate phases both exhibit inhomogeneous distribution. The population densities and the size fractions of the two precipitate phases are ranked from high to low in the following order: QS>SS>MS. (2) OCP, φcorr, φpit, Rct and RL of the plate......
