Study of the Solubility, Supersolubility, and Metastable Zone Width of Ternary System (NaCl + Na2SO4 + H2O) Containing Organic Impurity at 333.15 K
Journal of Chemical & Engineering Data, 2019Co-Authors: Li Zhu, Xiao-xia Zheng, Yongsheng Ren, Jing GaoAbstract:Typically, the industrial evaporation process is operated at a high evaporation rate in a nonequilibrium stable or dynamic state within a temperature range of 323 to 393 K. During this process, both the solubility and the crystallization of salt are affected by Organic impurities in the system. In this work, glutaraldehyde, one of the main Organic compounds in wastewater produced from the coal chemical, was selected as a representative Organic Impurity, and the chemical oxygen demand (COD) of glutaraldehyde solution was used to simulate the COD of highly saline coal chemical wastewater. The stable and metastable solid–liquid equilibria of the (Na2SO4–NaCl–H2O) system containing the Organic Impurity at 333.15 K were studied. The results showed that the solubility and supersolubility of Na2SO4 increased with the increase of COD. However, the solubility and supersolubility of NaCl had begun to increase when the COD value is around 450 mg L–1. When the COD value reached to 3290 mg L–1 (the content of actual w...

Influence of plating parameters and solution chemistry on the voiding propensity at electroplated copper–solder interface
Journal of Applied Electrochemistry, 2008Co-Authors: J. Wang, P. Kondos, C. Parks, P. Borgesen, D. W. Henderson, E. J. Cotts, N. DimitrovAbstract:Interfacial voiding in solder joints formed with Sn–Ag–Cu solder alloys and electroplated Cu was examined as a function of the plating solution chemistry and parameters. Galvanostatic Cu plating of ~10 μm thick Cu films was performed in a commercially available plating solution, and in model generic plating solutions. Analysis of the current voltage behavior along with Secondary Ion Mass Spectrometry studies of Organic Impurity content of two plated and a wrought copper samples, yielded a conclusion that for certain chemistry solutions (e.g., H_2SO_4 + CuSO_4 + Cl^− + PEG) and current density ranges above 2.5 mA cm^−2, Organic impurities were incorporated into the growing Cu. Solder joints were produced with a variety of electroplated Cu samples. These joints were, then, annealed at a temperature of 175 °C for 1 week, cross sectioned and examined. In general, it was observed that interfacial voiding in laboratory electroplated Cu layers was qualitatively similar to the unexplained voiding observed in some industrially plated Cu products. More specifically, it was found that the propensity for voiding could be correlated with specific electroplating parameters that in turn were associated with significant incorporation of Organic impurities in the Cu deposit.
