Abstract: The Transient Plane Source (TPS) technique was used to evaluate the thermal transport characteristics (such as thermal conductivity, thermal diffusivity, specific heat per unit volume) in multi-component Se_78-xTe₂₀Sn₂Pb_x glasses at room temperature. From the experimental results, it was noted that thermal conductivity decreased with lead (Pb) content in the ternary Se₇₈Te₂₀Sn₂ alloy. This can be explained in terms of the rise in density, molar volume, and mean bond energy of the quaternary alloy.
