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.Tellurium ma le mama e sili atu nai lo le 99.99% ua taʻua o le maualuga-mama o le tellurium. |
Talosaga: E faʻaaogaina e saunia ai le II-VI faʻapipiʻi semiconductor, solar cell, elemene liua thermoelectric, elemene faʻalili, moli-emitting diodes, suʻesuʻega faʻanatura faaniukilia, faʻamatalaga infrared ma isi mea faʻavae. |
