Tellurium compounds are chemical substances that contain the element tellurium, which is a metalloid found in group 16 of the periodic table. These compounds can form various types of bonds, including covalent and ionic, and are often used in electronics, glass manufacturing, and as catalysts in chemical reactions. Common tellurium compounds include tellurium dioxide (TeO2) and tellurium sulfide (TeS2). They exhibit unique properties, such as semiconductor behavior and the ability to form complex structures. Due to their diverse applications, tellurium compounds are of interest in materials science and industrial chemistry.
