| Abstract: | The saturated solutions of calcite were treated by the copper-zinc alloy in this paper. The microstrucuture, phase composition and infrared absorption spectra of the scale were examined by scanning electron microscope (SEM), X-ray diffraction (XRD) and fourier transform infrared spectrum (FTIR), respectively. Besides, the surface tension of the saturated solutions was tested, before and after treated with the alloy. On the basis, the effect of metal cations and galvanic cell action on the crystal structure ... |
