Tellurium wani nau'in ƙarfe ne mai ƙima mai alamar Te. Tellurium shine crystal-fari crystal na jerin rhombohedral, mai narkewa a cikin sulfuric acid, nitric acid, aqua regia, potassium cyanide da potassium hydroxide, wanda ba zai iya narkewa cikin ruwan sanyi da ruwan zafi da carbon disulfide. An sami babban tsabta mai tsabta ta hanyar amfani da tellurium foda a matsayin albarkatun kasa da kuma cirewa da kuma tacewa tare da sodium polysulfide. Tsaftar ya kasance 99.999%. Don na'urar semiconductor, gami, albarkatun albarkatun sinadarai da ƙari na masana'antu kamar simintin ƙarfe, roba, gilashi, da sauransu.
2. [Nature]
Tellurium yana da allotropy guda biyu, wato, baki foda, amorphous tellurium da silvery fari, luster metallic, da hexagonal crystalline tellurium. Semiconductor, bandgap 0.34 ev.
Daga cikin allotropy guda biyu na tellurium, ɗayan shine crystalline, ƙarfe, silvery-fari da gaggautsa, kama da antimony, ɗayan kuma foda ne amorphous, launin toka mai duhu. Matsakaicin yawa, ƙarancin narkewa da wurin tafasa. Ba karfe ba ne, amma yana gudanar da zafi da wutar lantarki sosai. A cikin dukkan sahabbansa wadanda ba karfe ba, shi ne mafi karafa.

Babban tsarki tellurium kristal daya sabon nau'in kayan infrared ne. Ana ƙara tellurium na al'ada zuwa ƙarfe da ƙarfe na jan karfe don haɓaka injin su da haɓaka taurin; a cikin farin simintin ƙarfe, tellurium na al'ada ana amfani da shi azaman mai daidaitawa na carbide don sanya ƙasa ta yi tauri da juriya; gubar, wadda ta ƙunshi ɗan ƙaramin adadin tellurium, ana ƙara shi a cikin gami don haɓaka injinsa da ƙara taurinsa, yana inganta juriya na kayan abu, da juriya da ƙarfi, kuma ana amfani da shi azaman kube don igiyoyi na ƙarƙashin ruwa; ƙara tellurium zuwa gubar yana ƙara taurinsa, kuma ana amfani dashi don yin faranti da nau'in baturi. Za a iya amfani da Tellurium azaman ƙari don haɓakar fashewar mai kuma azaman mai haɓakawa don shirye-shiryen ethylene glycol. Tellurium oxide ana amfani dashi azaman mai launi a cikin gilashi. Za'a iya amfani da tellurium mai girma a matsayin abin haɗawa da kayan wutan lantarki. Bismuth telluride abu ne mai kyau mai sanyi. Tellurium shine Jerin kayan semiconductor tare da mahaɗan telluride da yawa, irin su cadmium telluride, a cikin ƙwayoyin hasken rana.
A halin yanzu, masana'antar cdte siririn fim makamashin hasken rana yana haɓaka cikin sauri, wanda ake ɗauka a matsayin ɗayan fasahohin makamashin hasken rana.
