More info

Zinc Antimonide (ZnSb) materials are crucial components for the research, development, and production of advanced technologies that require optimum properties, performance, and quality.

Zinc Antimonide (ZnSb), (Zn3Sb2), (Zn4Sb3) is an inorganic chemical compound. The Zn-Sb system contains six intermetallics. Like indium antimonidealuminum antimonide, and gallium antimonide, it is a semiconducting intermetallic compound. It is used in transistorsinfrared detectors, and thermal imagers, as well as magnetoresistive devices.
