Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
Thermoelectric materials can be used to convert waste heat, such as solar energy and automobile exhaust, to electricity. A Bi0.45Sb1.55Te3 p-type cuboid was created using hydrothermal synthesis, cold pressing, and evacuated-and-encapsulated sintering in a Pyrex ampoule. The figure of merit (z) was determined by finding three transport parameters: electrical conductivity, thermopower, and thermal conductivity. The thermal conductivity measurements on the three (A, ...
