Incazelo Yomkhiqizo

Inokubonakala kwensimbi emhlophe esiliva, ukuminyana okungu-6.25 g / cm3, indawo yokuncibilika engu-452 ° C, indawo yokubilisa engu-1390 ° C, nokuqina kwe-2.5 (Mohs hardness). Kunezinhlobo ezimbili ze-allotropic, i-crystalline ne-amorphous. I-Tellurium isha emoyeni ngelangabi eliluhlaza futhi ikhiqize 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 nge-high-purity tellurium.

Isicelo

Isetshenziselwa ukulungisa ama-semiconductors ahlanganisiwe we-II-VI, amaseli elanga, izakhi zokuguqula i-thermoelectric, izakhi zesiqandisi, ama-diode akhipha ukukhanya, ukutholwa kwemisebe ye-nuclear, imitshina ye-infrared nezinye izinto eziyisisekelo.
