1. [Gabatarwa]
Tellurium wani sinadari ne mai kama da ƙarfe mai alamar Te. Tellurium wani lu'ulu'u ne mai launin azurfa-farin azurfa na jerin rhombohedral, mai narkewa a cikin sulfuric acid, nitric acid, aqua regia, potassium cyanide da potassium hydroxide, wanda ba ya narkewa a cikin ruwan sanyi da ruwan zafi da carbon disulfide. An sami tellurium mai tsarki ta hanyar amfani da foda tellurium a matsayin kayan masarufi da kuma cirewa da tacewa da sodium polysulfide. Tsabtace shine kashi 99.999%. Ga na'urorin semiconductor, gami, albarkatun sinadarai da ƙari na masana'antu kamar ƙarfe, roba, gilashi, da sauransu.
2. [Yanayi]
Tellurium yana da allotropy guda biyu, wato foda baƙi, amorphous tellurium da farin azurfa, mai walƙiya ta ƙarfe, da kuma hexagonal crystalline tellurium. Semiconductor, bandgap 0.34 ev.
Daga cikin allotropy guda biyu na tellurium, ɗaya shine crystalline, ƙarfe, fari-silvery kuma mai karyewa, yayi kama da antimony, ɗayan kuma shine foda mara tsari, launin toka mai duhu. Matsakaicin yawa, ƙarancin narkewa da wurin tafasa. Ba ƙarfe bane, amma yana gudanar da zafi da wutar lantarki sosai. Daga cikin dukkan abokan haɗinsa marasa ƙarfe, shine mafi ƙarfe.
3. [Aikace-aikace]
Tsaftataccen tellurium guda ɗaya sabon nau'in kayan infrared ne. Ana ƙara tellurium na al'ada a cikin ƙarfe da ƙarfe don inganta injin su da ƙara tauri; a cikin farin ƙarfe, ana amfani da tellurium na al'ada azaman mai daidaita carbide don sa saman ya yi tauri da juriya ga lalacewa; gubar, wacce ke ɗauke da ƙaramin adadin tellurium, ana ƙara ta a cikin ƙarfe don inganta injin sa da ƙara tauri, yana inganta juriyar lalata kayan, juriyar lalacewa da ƙarfi, kuma ana amfani da shi azaman sheath ga kebul na ƙarƙashin ruwa; ƙara tellurium zuwa gubar yana ƙara tauri, kuma ana amfani da shi don yin faranti da nau'in baturi. Ana iya amfani da Tellurium azaman ƙari ga masu haɓaka fashewar mai da kuma azaman mai haɓaka don shirya ethylene glycol. Ana amfani da Tellurium oxide azaman mai launi a cikin gilashi. Ana iya amfani da tellurium mai tsabta azaman kayan haɗin gwiwa a cikin kayan thermoelectric. Bismuth telluride abu ne mai kyau na refrigerant. Tellurium shine Jerin kayan semiconductor tare da mahaɗan telluride da yawa, kamar cadmium telluride, a cikin ƙwayoyin hasken rana.
A halin yanzu, masana'antar makamashin hasken rana mai siffar cdte tana ci gaba cikin sauri, wanda ake ɗauka a matsayin ɗaya daga cikin fasahohin makamashin hasken rana mafi kyau.
