Measuring Thermophysical Properties with Focus on Thermal Conductivity
Material Characterization with NETZSCH: Thermophysical properties are fundamental characteristics of materials that describe their behavior under thermal and/or physical changes. Learn from our NETZSCH experts about the latest technologies and methods for thermophysical properties determination and analysis.
Thermophysical properties are fundamental characteristics of materials that describe their behavior under thermal and/or physical changes. These include Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity, which determines how efficiently a material conducts heat. Equally important is the Specific Heat Capacity (cp)Heat capacity is a material-specific physical quantity, determined by the amount of heat supplied to specimen, divided by the resulting temperature increase. The specific heat capacity is related to a unit mass of the specimen.specific heat capacity, which indicates how much heat is required to increase the temperature of a mass. DensityThe mass density is defined as the ratio between mass and volume. Density and thermal expansion, describing the volume behavior when the temperature changes, are also relevant.
These properties play a crucial role in understanding how materials react to environmental factors such as temperature changes. The precise determination of these properties is of great importance for various fields, including materials science, engineering and physics.
