摘要: Abstract In the recent past, glass physicists have focused their attention on element lead as a modifier due to observation of carrier-type reversal in chalcogenide glasses for particular composition certain glassy systems after incorporation lead. Keeping this fact mind, some new quaternary been synthesized using Pb ternary Se78Te20Sn2 alloy parent glass. Specific heat studies made Se78−xTe20Sn2Pbx(0≤x≤6) alloys modulated differential scanning calorimetry (MDSC) technique. An extremely large increase specific values has observed at transition temperature. The dependence below temperature (Cpe) and (Cpg) also explained.
