Uphawu.

Inokubonakala kwesinyithi esimhlophe-emhlophe, ubuninzi be-6.25 g / cm3, indawo yokunyibilika ye-452 ° C, indawo yokubilisa ye-1390 ° C, kunye nobunzima be-2.5 (ubunzima be-Mohs).Kukho iifom ezimbini ze-allotropic, i-crystalline kunye ne-amorphous.I-Telluriumitshisa emoyeni ngedangatye eliluhlaza kwaye ivelise i-tellurium dioxide;inokusabela ngeehalogens kodwa hayi ngesulfure kunye neselenium.Inyibilika kwi-asidi ye-sulfuric, i-nitric acid, i-potassium hydroxide kunye nesisombululo se-potassium cyanide.Ukugqithiswa kobushushu obungalunganga kunye nokuhanjiswa kombane.I-Tellurium enobunyulu obungaphezulu kwe-99.99% ibizwa ngokuba yi-high-purity tellurium.

Isicelo

Isetyenziselwa ukulungiselela i-II-VI i-semiconductors edibeneyo, iiseli zelanga, i-thermoelectric conversion elements, i-refrigeration elements, ii-diode ezikhupha ukukhanya, ukubonwa kwemitha yenyukliya, i-infrared detectors kunye nezinye izinto ezisisiseko.
