Novel technology of purification of copper electrolyte

The effects of arsenic with different valence states on the purification of copper electrolyte were studied and a novel technology of purification of copper electrolyte by copper arsenite was proposed. The results show that the purification performance of As（Ⅲ） compounds is better than that of As（Ⅴ） compounds. The purification technology by copper arsenite has the advantages of simple operation, high purification performance and low cost in comparison with other technologies and its appropriate purification conditions are that copper arsenite concentration is 18 g/L, reaction temperature is 65 ℃ and reaction time is 8 h. The removal rates of Sb and Bi are 53.22% and 58.67% respectively under these conditions. The purification principle show that a kind of yellow precipitate mainly composed of arsenic, antimony （ Ⅴ ）, bismuth and oxygen forms in electrolyte after copper arsenite is added, and consequently antimony and bismuth are removed from electrolyte.     

熔体处理对一种Inconel 718C改型高温合金组织与性能的影响

在试验合金中,1600℃熔体处理对凝固后组织和性能产生显著影响。经1600℃熔体处理后,合金样品二次枝晶间距显著降低,元素偏析情况得到有效改善,凝固过程析出的TCP相数量明显减少,热处理后γ″析出相也更加细小均匀。熔体处理对合金室温和700℃拉伸强度影响不大,但却显著提高合金的拉伸塑性和700℃/620MPa持久性能。在1600℃熔体处理10min时,合金的综合力学性能最佳;延长熔体处理时间至15min时,合金力学性能呈下降趋势。

Hydriding-dehydriding properties of Mg2Ni alloy modified by ball-milling in tetrahydrofuran

A new approach of ball-milled Mg2Ni in tetrahydrofuran (THF) to improve the hydriding kinetics of Mg2Ni alloy is suggested and studied. It is found that the modified alloy displayed the improved activity for hydriding even at relatively low temperature (e.g., 323-373 K). In the case of the sample milled in THF for 20 h, the hydrogen content (mass fraction) reaches 1.6 % at 323 K, 2.1% at 348 K and 3.4% at 448 K, respectively. The use of THF during grinding led to the change of the structure, which is reflected by the broadening and weakening of the diffraction peaks in the XRD spectra. The XPS analysis shows that Mg (2s) binding energy peak of Mg2Ni after modification shifted from a lower binding energy to a higher one, indicating the charge transference between Mg and THF and the formation of catalytically active electron donor-acceptor (EDA) complexes on the surface of modified Mg2Ni alloy.
