Abstract : Thermal conductivity, a critical material property, can be measured using various methods, each suited to different applications and material types. This study reviews prominent techniques including the steady-state and transient methods. The steady-state methods, such as the guarded hot plate and heat flow meter techniques, involve maintaining a constant temperature gradient and measuring heat flux through the material. In contrast, transient methods, like the laser flash method and transient hot-wire technique, assess thermal conductivity by analyzing temperature changes over time following a brief thermal disturbance. Each method's accuracy, sample requirements, and application scope are discussed, providing insights into selecting the appropriate technique based on material characteristics and measurement conditions. This review aims to guide researchers in choosing optimal methods for accurate thermal conductivity assessment in diverse scientific and industrial contexts.
