| Uiga: O loʻo i ai se foliga uʻamea siliva-paʻepaʻe, o le mamafa o le 6.25 g / cm3, o le liusua o le 452 ° C, o le vevela o le 1390 ° C, ma le maaa o le 2.5 (Mohs faigata). E lua ituaiga allotropic, tioata ma amorphous.Telluriummu i le ea ma se mumu lanumoana ma maua ai le tellurium dioxide; e mafai ona tali i halogen ae le o le sulfur ma seleni. Solu i le sulfuric acid, nitric acid, potassium hydroxide ma le potassium cyanide solution. Le lelei le fa'afefe o le vevela ma le fa'aulu eletise.Telluriumfaʻatasi ai ma le mama o le sili atu i le 99.99% ua taʻua o le tellurium maualuga-mama. |
| Talosaga: E faʻaaogaina e saunia ai le II-VI faʻapipiʻi semiconductor, solar cell, elemene liua thermoelectric, elemene pusaaisa, moli-emitting diodes, suʻesuʻega faʻanatura faaniukilia, faʻamatalaga infrared ma isi mea faʻavae. |
