1. [Isingeniso]
I-Tellurium iyisici esicishe sibe yinsimbi esinophawu lwe-Te. I-Tellurium iyikristalu elimhlophe njengesiliva lochungechunge lwe-rhombohedral, elincibilika ku-sulfuric acid, i-nitric acid, i-aqua regia, i-potassium cyanide kanye ne-potassium hydroxide, elingancibiliki emanzini abandayo nashisayo kanye ne-carbon disulfide. I-tellurium emsulwa kakhulu itholakale ngokusebenzisa i-tellurium powder njengezinto zokusetshenziswa kanye nokukhipha nokucwenga nge-sodium polysulfide. Ubumsulwa babungu-99.999%. Kwedivayisi ye-semiconductor, ama-alloys, izinto zokusetshenziswa zamakhemikhali kanye nezithasiselo zezimboni ezifana nensimbi ephonswe, irabha, ingilazi, njll.
2. [Imvelo]
I-Tellurium ine-allotropy ezimbili, okungukuthi, i-powder emnyama, i-tellurium engenasimo kanye ne-silvery white, i-metallic luster, kanye ne-hexagonal crystalline tellurium. I-semiconductor, i-bandgap engu-0.34 ev.
Kuma-allotropy amabili e-tellurium, enye i-crystalline, i-metallic, i-silver-white futhi iyaphuka, ifana ne-antimony, kanti enye i-amorphous powder, i-dark grey. I-medium density, i-melting ephansi kanye ne-bolling point. Ayiyona insimbi, kodwa iphatha ukushisa kanye nogesi kahle kakhulu. Kuzo zonke izihlobo zayo ezingeyona insimbi, iyona ensimbi kakhulu.
3. [Isicelo]
Ikristalu eyodwa ye-tellurium emsulwa kakhulu uhlobo olusha lwezinto ze-infrared. I-tellurium evamile ingezwa kuma-alloy ensimbi nethusi ukuze kuthuthukiswe ukusebenza kwawo futhi kwandiswe ubulukhuni; ngensimbi emhlophe, i-tellurium evamile isetshenziswa njengesiqinisi se-carbide ukwenza ubuso buqine futhi bumelane nokuguguleka; i-lead, equkethe inani elincane le-tellurium, ifakwa ku-alloy ukuze kuthuthukiswe ukusebenza kwayo futhi kwandiswe ubulukhuni bayo, ithuthukisa ukumelana nokugqwala kwezinto, ukumelana nokuguguleka namandla, futhi isetshenziswa njengesigxobo sezintambo zangaphansi kolwandle; ukwengeza i-tellurium ku-lead kwandisa ubulukhuni bayo, futhi kusetshenziselwa ukwenza amapuleti ebhethri nohlobo. I-Tellurium ingasetshenziswa njengesithasiselo sama-catalyst okuqhekeka kwe-petroleum kanye nesithasiselo sokulungiselela i-ethylene glycol. I-Tellurium oxide isetshenziswa njengesithako sombala engilazini. I-tellurium emsulwa kakhulu ingasetshenziswa njengengxenye yokuhlanganisa ezintweni ze-thermoelectric. I-Bismuth telluride iyinto enhle yokuqandisa. I-Tellurium uhlu lwezinto ze-semiconductor ezinama-compounds amaningana e-telluride, njenge-cadmium telluride, kumaseli elanga.
Njengamanje, imboni yamandla elanga e-CDTE thin film ithuthuka ngokushesha, okubhekwa njengobunye bobuchwepheshe bamandla elanga obuthembisayo kakhulu.
