TeAs2 is a tellurium arsenide ceramic compound belonging to the chalcogenide ceramic family, characterized by strong covalent bonding between tellurium and arsenic atoms. This material is primarily of research interest rather than established industrial production, with potential applications in optoelectronic and infrared optical systems where its transparency and refractive properties in the infrared region would be leveraged. Engineers would consider TeAs2 for specialized niche applications requiring wide optical bandgaps and thermal stability, though commercial alternatives like zinc selenide and germanium remain more mature for infrared windows and lenses.
