Factors influencing thermal conductivity

Free electrons. Metals are having more free electrons compared to that of liquid and gases, so metal are good conductors of heat due to the migration of free electrons. ...

Purity of material. ...

Effect of forming. ...

High temperature. ...

Pressure. ...

Density. ...

Crystalline structure.

"Thermal conductivity λ is defined as ability of material to transmit heat and it is measured in watts per square metre of surface area for a temperature gradient of 1 K per unit thickness of 1 m". Therefore, specific thermal conductivity is calculated as: where: = specific thermal conductivity (W/(K. m))
