The results show that Sb addition can diminish the crystal grain, but the content of segregative phase at crystal boundary increases, and the current efficiency of material is low. Compared with Sb addition, Sn addition can also diminish the crystal grain, the current efficiency increases, the content of segregative phase at crystal boundary reduces, but diffusional corrosion of the anode surface is not uniform. The cooperation of Sb and Sn can prevent Si from segregating effectively and enhance the current efficiency obviously. At the same time, anode materials have preferable surface dissolution characteristics.

结果表明： Sb具有细化晶粒的作用，但晶界存在较多偏析相，电流效率偏低；与Sb相比较， Sn也具有细化晶粒的作用，电流效率有所提高，晶界偏析相较少，但阳极的表面腐蚀溶解不均匀； Sn和Sb的协同作用在于能有效地抑制Si的偏析，显著提高阳极的电流效率，使得阳极表面具有良好的腐蚀溶解性。

From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics.
