Ca2TeO4

Ca2TeO4 is a chemical compound with the formula Calcium Tellurite. It is an inorganic solid that crystallizes in the monoclinic crystal system. The structure consists of calcium cations and tellurite anions. Tellurite anions are characterized by a pyramidal [TeO3]2- unit. In Ca2TeO4, these tellurite units are linked by calcium ions.

This compound can be synthesized through various solid-state reactions, typically involving the heating of precursor oxides such as calcium oxide (CaO) and tellurium dioxide (TeO2) at elevated temperatures. The precise synthesis conditions, including temperature, duration, and stoichiometry of reactants, influence the resulting phase purity and morphology of the Ca2TeO4 product.

Ca2TeO4 has been investigated for potential applications in areas such as photocatalysis and as a component in solid oxide fuel cells. Its electronic and optical properties are of interest for these technological uses. Research into its specific properties and synthesis methods is ongoing to better understand its capabilities and limitations.
