As-containing wastewater till pH value was 6. Green copper arsenite was prepared after copper sulfate was added into the neutralized wastewater when the molar ratio of Cu to As was 2?1 and pH value......
based cermets were prepared by sintering method under controlled atmosphere, and their electrolysis corrosion in aluminum electrolysis at 960 ℃ was examined. Based on the studies of the microstructure and phase composition after sintering, surface morphology and composition after electrolysis, impurity content in electrolyte and cathode aluminum, the effects of BaO, Yb2O3 and CoO additive......
migration, so a lower sintering temperature was favorable for the microstructure of electrolysis. Consequently, the cathodic conductivity may be improved, but the microstructure became compact with the increase of sintering temperature. The cathodic products at different temperatures indicated that the cathodic conductivity was more important for electrolysis.关键词:......

Effect of additive on corrosion resistance of NiFe2O4 ceramics as inert anodes XI Jin-hui(席锦会)1, XIE Ying-jie(谢英杰)2, YAO Guang-chun(姚广春)2, LIU Yi-han(刘宜汉)2 1. School of Materials Science...; Abstract: In order to improve the corrosion resistance of NiFe2O4 ceramics as inert anode, additive V2O5 was added to raw materials NiO and Fe2O3. The inert anodes of nickel-ferrite ceramics were prepared......
the copper electrodeposition mechanism through their adsorption on the cathodic surface. In addition, scanning electron microscope (SEM) and X-ray diffraction analyses reveal that the presence of these additives leads to more leveled and fine-grained cathodic deposits without changing the crystal structure of the electrodeposited copper but strongly affects the crystallographic orientation......
