Tin-silver-zinc alloy is a new tin alloy, due to its green electronics industry as well as in a wide range of applications, so much attention, but its physical properties have not studied systematically. This article was prepared by vacuum arc melting the Sn 96.5-x Ag ( 3.50Zn x (x = 0, 1, 1.5, 2) sample and intermetallic compounds (Ag3Sn and AgZn sample), using X-ray diffraction, differential scanning calorimetry and physical properties measurement system, the structure of the sample, melting point, thermal properties and electrical transport properties have been studied. Sn < sub> 96.5 Ag ( 3.50 samples of Sn phase, Ag3Sn phase two-phase composition, and Sn 96.5-x Ag ( 3.50 Zn x (x = 1, 1.5, 2) samples were from the Sn-, Ag3Sn AgZn phase and phase-phase, of which the phase of the characteristic peaks AgZn incorporation of Zn increased with increasing the amount of . Sn 96.5-x Ag ( 3.50Zn x (x = 1, 1.5, 2) the melting point of the sample does not change with the incorporation of Zn change and change, respectively, 508 K, 502 K and 504 K. phonon specific heat at low temperature interval deviation Debye model (there Boson peak), analysis indicates that this is the local vibration (Einstein vibration) caused electrical resistivity in the entire temperature range to meet Matthiessen's law, that the electron-phonon scattering plays a major role. 160 K is the thermal conductivity of a cut-off point, the temperature above the electronic thermal conductivity plays a dominant role, to meet the Wiedemann-Franz law and This is below the temperature phonon thermal conductivity plays a dominant role. Sn95.5Ag ( 3.50Zn1 and Sn94.5Ag ( 3.50Zn2 sample Seebeck coefficient versus temperature curve showing the same rules in the low temperature region is positive, while in the high temperature zone is negative. Ag3Sn samples showed a single phase structure, the phonon specific heat and tin-silver-zinc samples the same trend, at low temperatures deviate from the Debye model range is also caused by the localized vibrational of its Einstein temperature than tin-silver-zinc alloy, low, indicating that Sn 96.5 Ag ( 3.50 Zn alloy is added after the cause of vibration Einstein intensity. resistance at very low temperatures (about 60 K below) in the impurity scattering and electron-phonon scattering electron quantum interference term between the major role, but in the high temperature range, the quantum effect as the temperature elevated weakened, then electron and phonon scattering plays a major role in it.
