be controlled by the anodic or cathodic reaction, but not by diffusion. GUAN et al [5] reported the dissolution behavior of gold/copper alloys in the aerated cyanide solutions and found that the dissolution rate... -130 mV and the peak slightly shifted with increasing rotation rate, but the peak current density increased remarkably. Simultaneously, the effect of electrode speed on the anode dissolution behavior......
J. Cent. South Univ. Technol. (2011) 18: 1833-1837 DOI: 10.1007/s11771-011-0910-4 Dissolution behavior of calcium-magnesium-silicate glass fiber LIU Hao(刘浩), WANG Xi-tang(王玺堂), ZHANG Bao-guo(张保国... Berlin Heidelberg 2011 Abstract: The dissolution behavior of CaO-MgO-SiO2 glass fiber was investigated by scanning electron microscopy (SEM), Fourier-transform infrared spectrometer (FTIR......
Dissolution behavior of Cu in Cu-Ag and Cu-P brazing alloys using weld brazingLI Yi-nan1, 2, WANG Chang-wen1, PENG Zi-long2, YAN Jiu-chun1, LIU Xue-song1(1.

; KOH; dissolution behavior; mechanism; solid-solution 1 Introduction Tantalum and niobium are important rare refractory metals and are widely used in steel, electronic and other high-tech industries... system. The aim of this work is to investigate the dissolution behavior of Nb2O5, Ta2O5 and their mixture in KOH molten salt and H2O system. And the interaction between niobium and tantalum......
; Abstract: The dissolution behavior of solid nickel in static liquid zinc saturated with Fe at 723 K was studied. The results show... zinc, dissolution of the solid in liquid phase and formation of intermetallic compound layers at the interface take place simultaneously. In previous work[9], the dissolution behavior of solid nickel......
of Al2O3 in basic cryolite melts experimentally for 3≤r(cryolite ratio)≤12.5 at 1 300 K. QIU et al developed transparent quartz electro- bath in 1985. Dissolution behavior of alumina can... and studied the dissolution behavior of alumina in molten cryolite. It is found that the dissolution process of alumina is divided into two stages: rapid dissolution and peeling off dissolution of alumina......
