Tellurium oxides are chemical compounds formed by the element tellurium and oxygen. They typically exist in various oxidation states, with tellurium dioxide (TeO2) being the most common. These oxides are often used in materials science and electronics due to their unique properties. In addition to their industrial applications, tellurium oxides can also play a role in the production of semiconductors and photovoltaic cells. Their ability to form glasses and ceramics makes them valuable in the manufacturing of optical materials and other advanced technologies.
