| Hunhu:Iine silver-white simbi chitarisiko, density ye6.25 g/cm3, kunyungudika kwe452 ° C, kuvira kwe1390 ° C, uye kuoma kwe2.5 (Mohs kuoma). Kune maviri allotropic mafomu, crystalline uye amorphous.Telluriuminopisa mumhepo nemurazvo webhuruu uye inobudisa tellurium dioxide; inogona kuita nema halogens asi kwete nesarufa uye selenium. Soluble mu sulfuric acid, nitric acid, potassium hydroxide uye potassium cyanide solution. Kusaita kupisa kwekutamisa uye magetsi conductivity.Telluriumnekuchena kweinopfuura 99.99% inonzi high-purity tellurium. |
| Chishandiso:Inoshandiswa kugadzirira II-VI komputa semiconductors, solar masero, thermoelectric shanduko zvinhu, firiji zvinhu, light-emitting diodes, nyukireya radiation kuona, infrared detectors uye zvimwe zvakakosha zvinhu. |
