1. [Isingeniso]
I-Tellurium iyingxenye ye-quasi-metallic enophawu u-Te. I-Tellurium iyikristalu emhlophe esiliva yochungechunge lwe-rhombohedral, encibilika ku-sulfuric acid, i-nitric acid, i-aqua regia, i-potassium cyanide ne-potassium hydroxide, engancibiliki emanzini abandayo nashisayo kanye ne-carbon disulfide. Ukuhlanzeka okuphezulu kwe-tellurium kutholwe ngokusebenzisa i-tellurium powder njengento eluhlaza kanye nokukhipha nokucwenga nge-sodium polysulfide. Ubumsulwa bebungu-99.999%. Okwedivayisi ye-semiconductor, ama-alloys, izinto zokusetshenziswa zamakhemikhali nezithasiselo zasezimbonini njenge-cast iron, irabha, ingilazi, njll.
2. [Imvelo]
I-Tellurium ine-allotropy emibili, okungukuthi, impushana emnyama, i-amorphous tellurium ne-silvery white, i-metallic luster, ne-hexagonal crystalline tellurium. I-Semiconductor, i-bandgap 0.34 ev.
Kuma-allotropy amabili e-tellurium, eyodwa i-crystalline, i-metallic, i-silvery-white ne-brittle, efana ne-antimony, kanti enye i-amorphous powder, grey emnyama. Ukuminyana okuphakathi, ukuncibilika okuphansi kanye nendawo yokubilisa. Ayiyona insimbi, kodwa ikuphatha kahle kakhulu ukushisa nogesi. Kubo bonke abangani bayo abangeyona eyensimbi, iyinsimbi kakhulu.
3. [Isicelo]
I-high purity tellurium crystal single iwuhlobo olusha lwempahla ye-infrared. I-tellurium evamile yengezwe ku-alloys yensimbi neyethusi ukuze kuthuthukiswe ukusebenza kwayo nokwandisa ubulukhuni; ku-iron cast emhlophe, i-tellurium evamile isetshenziswa njenge-stabilizer ye-carbide ukwenza ubuso buqine futhi bugqoke; ukuhola, okuqukethe inani elincane le-tellurium, yengezwe ku-alloy ukuze kuthuthukiswe ukusebenza kwayo futhi kwandiswe ubulukhuni bayo, ithuthukisa ukumelana nokugqwala kwezinto, ukumelana nokugqoka namandla, futhi isetshenziswa njenge-sheath yezintambo ezihamba ngaphansi kolwandle; ukwengeza i-tellurium ekuholeni kwandisa ubulukhuni bayo, futhi isetshenziselwa ukwenza amapuleti ebhethri kanye nohlobo. I-Tellurium ingasetshenziswa njengesengezo se-petroleum cracking catalysts futhi njenge-catalyst yokulungiswa kwe-ethylene glycol. I-Tellurium oxide isetshenziswa njengombala engilazini. Ukuhlanzeka okuphezulu kwe-tellurium kungasetshenziswa njengengxenye ye-alloying ezintweni ze-thermoelectric. I-Bismuth telluride iyinto enhle yesiqandisi. I-Tellurium iwuhlu lwezinto zokwakha ze-semiconductor ezinezinhlanganisela ze-teluride eziningana, njenge-cadmium telluride, kumaseli elanga.
Njengamanje, imboni ye-cdte yefilimu emincane yamandla elanga ikhula ngokushesha, okubhekwa njengobunye bobuchwepheshe obuthembisa kakhulu bamandla elanga.
