Isici: Inokubonakala kwensimbi esiliva-mhlophe, ukuminyana okungu-6.25 g / cm3, indawo yokuncibilika engu-452 ° C, indawo yokubilisa engu-1390 ° C, kanye nobulukhuni obungu-2.5 (ukuqina kwe-Mohs).Kunezinhlobo ezimbili ze-allotropic, i-crystalline ne-amorphous.I-Telluriumukushisa emoyeni ngelangabi eliluhlaza futhi kukhiqize i-tellurium dioxide;ingasabela ngama-halogen kodwa hhayi ngesulfure ne-selenium.Incibilika ku-sulfuric acid, i-nitric acid, i-potassium hydroxide nesisombululo se-potassium cyanide.Ukudluliswa kokushisa okungekuhle kanye nokusebenza kahle kukagesi.I-Tellurium enobumsulwa obungaphezu kuka-99.99% ibizwa ngokuthi i-high-purity tellurium. |
Isicelo: Isetshenziselwa ukulungisa ama-semiconductors ahlanganisiwe we-II-VI, amaseli elanga, izakhi zokuguqulwa kwe-thermoelectric, izakhi zesiqandisi, ama-diode akhipha ukukhanya, ukutholwa kwemisebe yenuzi, imitshina ye-infrared nezinye izinto eziyisisekelo. |
