telluroxides

Telluroxides are a class of chemical compounds containing tellurium and oxygen. These compounds can exist in various oxidation states for tellurium, most commonly +4 and +6. Tellurium dioxide (TeO2) is a well-known example, existing in both amorphous and crystalline forms. Crystalline tellurium dioxide is a white solid with a high refractive index and is used in optical devices. Tellurium trioxide (TeO3) is another telluroxide, typically a reddish-yellow solid. These oxides can be formed through the oxidation of tellurium metal or tellurium-containing compounds. Telluroxides exhibit amphoteric behavior, meaning they can react with both acids and bases. For instance, tellurium dioxide reacts with strong bases to form tellurites and with strong acids to form tellurium salts. Some telluroxides have found applications in catalysis, ceramics, and as intermediates in the synthesis of other tellurium compounds. The study of telluroxides is part of inorganic chemistry and materials science.
