Calcium telluride (CaTe₂) is an inorganic ceramic compound belonging to the metal telluride family, characterized by ionic bonding between alkaline-earth calcium and chalcogen tellurium. This material is primarily investigated in semiconductor and photovoltaic research contexts rather than established in high-volume industrial production, with potential applications in thermoelectric devices and narrow-bandgap semiconductor systems where tellurium-based compounds offer tunable electronic properties.
