Tellurium ke karolo ea quasi-metallic e nang le letšoao la Te. Tellurium ke kristale e tšoeu ea silevera ea letoto la rhombohedral, e qhibilihang ka sulfuric acid, nitric acid, aqua regia, potassium cyanide le potassium hydroxide, e ke keng ea qhibiliha metsing a batang le a chesang le carbon disulfide. High purity tellurium e ile ea fumanoa ka ho sebelisa phofo ea tellurium e le lisebelisoa tse tala le ho ntša le ho hloekisa ka sodium polysulfide. Bohloeki e ne e le 99.999%. Bakeng sa sesebelisoa sa semiconductor, li-alloys, lisebelisoa tse tala tsa lik'hemik'hale le lisebelisoa tsa indasteri tse kang tšepe e entsoeng ka tšepe, rabara, khalase, joalo-joalo.
2. [Tlhaho]
Tellurium e na le allotropy tse peli, e leng, phofo e ntšo, amorphous tellurium le silvery white, metallic luster, le hexagonal crystalline tellurium. Semiconductor, bandgap 0.34 ev.
Har'a li-allotropy tse peli tsa tellurium, e 'ngoe ke crystalline, metallic, silvery-white le brittle, e tšoanang le antimony,' me e 'ngoe ke phofo ea amorphous, e bohlooho bo lefifi. Boima bo mahareng, ho qhibiliha ho tlase le ntlha e belang. Ha se tšepe, empa e tsamaisa mocheso le motlakase hantle haholo. Har'a balekane bohle ba eona bao e seng tšepe, ke tšepe e matla ka ho fetisisa.

High purity tellurium single crystal ke mofuta o mocha oa thepa ea infrared. Telurium e tloaelehileng e kenngoa ho li-alloys tsa tšepe le tsa koporo ho ntlafatsa machinability ea tsona le ho eketsa boima; ka tšepe e tšoeu e entsoeng ka tšepe, tellurium e tloaelehileng e sebelisoa e le stabilizer ea carbide ho etsa hore holim'a metsi a be thata le hore a se ke a apara; lead, e nang le palo e nyane ea tellurium, e eketsoa ka motsoako ho ntlafatsa machinability ea eona le ho eketsa boima ba eona, e ntlafatsa ho hanyetsa ho bola ha thepa, ho hanyetsa le ho sebetsa ka matla, 'me e sebelisoa e le sheath bakeng sa lithapo tse tsamaeang ka tlas'a metsi; ho eketsa tellurium ho etella pele ho eketsa boima ba eona, 'me e sebelisetsoa ho etsa lipoleiti tsa betri le mofuta. Tellurium e ka sebelisoa e le tlatsetso bakeng sa li-catalysts tsa petroleum cracking le e le mohloli oa ho lokisetsa ethylene glycol. Tellurium oxide e sebelisoa e le colorant ka khalase. High purity tellurium e ka sebelisoa e le motsoako oa motsoako oa thepa ea thermoelectric. Bismuth telluride ke thepa e ntle ea sehatsetsing. Tellurium ke Lethathamo la lisebelisoa tsa semiconductor tse nang le metsoako e mengata ea telluride, joalo ka cadmium telluride, liseleng tsa letsatsi.
Hajoale, indasteri ea cdte filimi e nyane ea matla a letsatsi e ntse e tsoela pele ka potlako, e nkuoang e le e 'ngoe ea mahlale a ts'episang a matla a letsatsi.
