Antimony Foil

Antimony Foil is characterized by its semi-metallic nature, moderate electrical conductivity, and excellent resistance to chemical attack. It exhibits a unique combination of brittleness and stability, with a crystalline structure that supports stable performance under varying thermal conditions. These properties make it well-suited for use in electronics, energy storage, and thermoelectric applications. Industries employing Antimony Foil include semiconductor manufacturing, specialty alloys production, and renewable energy systems. Specific uses include electrodes in advanced batteries, thermoelectric modules for waste heat recovery, and precision solder alloys for hermetic microelectronic packaging. In research and innovation, antimony's tunable electronic band structure and alloying versatility enable the development of high-performance devices and next-generation energy conversion systems. Its consistent chemical and thermal stability ensures lasting value in both cutting-edge scientific research and demanding industrial processes.
