Ingcaciso yeMveliso

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-Tellurium iyatshisa 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.
