Tellurium In Ceramics

Tellurium has been used to vulcanise rubber to tint glass and ceramics in solar cells in rewritable cds and dvds and as a catalyst in oil refining.

Tellurium in ceramics. At the same time tellurium is more metallic than sulfur and it shares many properties with the metalloid class of elements. Tellurium is a chemical element with the symbol te and atomic number 52. It is a brittle mildly toxic rare silver white metalloid tellurium is chemically related to selenium and sulfur all three of which are chalcogens it is occasionally found in native form as elemental crystals. Hence its chemistry shares many similarities with sulfur and it can be easily incorporated into sulfur compounds manthiram explains in an email.

Tellurium is also used in the electronics industry for example with cadmium and mercury to form photosensitive semiconductors. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Yb 3 er 3 upconversion nanocrystals were successfully prepared via a new sol gel route for the first time. Tellurium sits two positions below sulfur in the periodic table.

Cadmium telluride cdte is used as a thin film in solar panels to convert sunlight into electricity. Tellurium is used as a coloring agent in ceramics. It can be doped with silver gold copper or tin in semiconductor applications. Tellurium is a semiconductor and is frequently doped with copper tin gold or silver.

Transparent bulk glass ceramics gcs containing β nay f 4. Tellurium is primarily used as an alloying agent. Small amounts of tellurium are added to copper and stainless steel to make them easier to machine and. Tellurium is also used to color glass and ceramics and is one of the primary ingredients in blasting caps.

Adding tellurium to lead improves the strength and hardness of the metal and decreases corrosion. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.
