What Are Extruded Thermoelectric Materials?
Extruded Thermoelectric Materials are specialized materials manufactured through a high-pressure extrusion process that forms thermoelectric compounds into controlled shapes such as rods, plates, or microstructures.
Thermoelectric materials have the ability to convert heat energy directly into electrical energy or perform the reverse process—converting electricity into cooling or heating. This effect is primarily based on the Seebeck effect and Peltier effect.
Extrusion improves the internal grain structure of thermoelectric materials, which can enhance:
-
Electrical conductivity
-
Mechanical strength
-
Thermal stability
-
Material density
This manufacturing method also allows precise control over geometry, making it ideal for advanced cooling modules and micro thermoelectric devices.
