| Khalidwe: Ili ndi mawonekedwe azitsulo zoyera zasiliva, kachulukidwe ka 6.25 g / cm3, malo osungunuka a 452 ° C, malo otentha a 1390 ° C, ndi kuuma kwa 2.5 (kuuma kwa Mohs). Pali mitundu iwiri ya allotropic, crystalline ndi amorphous.Telluriumkuyaka mumlengalenga ndi lawi la buluu ndikupanga tellurium dioxide; imatha kuchita ndi ma halojeni koma osati ndi sulfure ndi selenium. Kusungunuka mu sulfuric acid, nitric acid, potaziyamu hydroxide ndi potaziyamu cyanide solution. Kusayenda bwino kwa kutentha ndi kusuntha kwamagetsi.Telluriumndi chiyero choposa 99.99% amatchedwa high-purity tellurium. |
| Ntchito: Amagwiritsidwa ntchito pokonzekera II-VI pawiri semiconductors, ma cell solar, thermoelectric conversion elements, refrigeration elements, light-emitting diodes, nyukiliya radiation kuzindikira, zowunikira infuraredi ndi zipangizo zina zofunika. |
