Measuring the thermal conductivity of Sn-based alloys are vital since they are mainly used in soldering and temperature sensitive materials in sprinklers.
λ= Q4πd ∆Td ∆ln t (2.2) When measuring the thermal conductivity of the electrical conductivity materials such as metals and alloys, the electrical leakage from the hot wire to the sample has to be avoided.
To avoid starting convention in the oil bath, a cover made of the heat insulating material was put onto it in measurements.
In materials, both electron and lattice contribute to the thermal conduction properties.
