Abstract Scope |
Reducing carbon emissions and improving energy sustainability necessitates alternative technologies for recovering industrial waste heat, which accounts for 20–50% of energy loss in conventional power systems. Thermoelectric materials offer a promising solution by directly converting waste heat into electricity. The misfit layered p-type oxide Bi2Ca2Co2-xOy has emerged as a viable candidate for high-temperature, air-stable thermoelectric applications. This work investigates an additive manufacturing approach for fabricating Bi2Ca2Co2-xOy ceramics, enabling a direct transformation from precursor powders to functional thermoelectric components. Compared to conventional techniques, additive manufacturing offers enhanced control over geometry, microstructure, and material efficiency while minimizing processing complexity. Optimization of powder synthesis, printing parameters, and thermal treatment conditions is presented to achieve preferred orientation and improved thermoelectric performance. These findings demonstrate the potential of additive manufacturing as a scalable and energy-efficient alternative for the production of complex oxide thermoelectric materials. |
