metal

· JVASP-40767· ZrFeSb

ZrFeSb is an intermetallic compound composed of zirconium, iron, and antimony, belonging to the half-Heusler alloy family. This material is primarily investigated for thermoelectric applications due to its potential to convert waste heat into electrical energy efficiently, making it attractive for power generation and thermal management in automotive and industrial systems. ZrFeSb is largely a research-phase material rather than a widely commercialized alloy, with ongoing development focused on optimizing its thermoelectric figure of merit and stability for practical energy harvesting devices.
