Tellurium (symbol Te) is the chemical element with atomic number 52 and located in group 16 of the periodic table. It is a metallic solid that is rare in nature, but found naturally in several ores.

Tellurium is most stable in the solid state, and can be melted at a temperature of 449.5°C and vaporized at a temperature of 900°C. It is characterized by a shiny metallic color and a slight graying in moist air. It corrodes easily in water and ammonia.

Tellurium has many uses, including in alloys, chemicals, electronics, and industry. It is widely used to produce electronic components, televisions and refrigerators. Tellurium is also used to produce mechanical components such as screws, bolts, and castings.

Tellurium is also an essential component of optical materials. It is used in the manufacture of glasses and optical fibers, as well as in certain semiconductor materials such as diodes and transistors.

In addition, tellurium is widely used as a food additive, especially in iodized salts. It is also used in the manufacture of catalysts, especially tellurium oxide catalysts.
