In5Bi3

In5Bi3 is an intermetallic ceramic compound composed of indium and bismuth, belonging to the class of binary metal-rich ceramics. This material is primarily of research interest rather than established industrial use, with potential applications in thermoelectric devices and semiconductor applications where the combination of these low-toxicity heavy metals offers interesting electronic and thermal properties. Compared to traditional thermoelectric materials, indium-bismuth compounds are being investigated for their ability to operate effectively at moderate temperatures while maintaining lower environmental impact than some legacy alternatives.
