Whakaahuatanga Hua

He ahua whakarewa hiriwa-ma, he kiato o 6.25 g / cm3, he ira whakarewa o 452 ° C, he koropupu o 1390 ° C, me te pakeke o 2.5 (Mohs pakeke). E rua nga momo allotropic, he tioata me te amorphous. Ka wera te Tellurium i te rangi me te mura kahurangi ka whakaputa te telurium dioxide; ka taea e ia te tauhohe ki nga halogens engari kaua ki te whanariki me te selenium. Wairewa ki te waikawa pungatara, waikawa nitric, pāhare waihā me te otinga pāhare pāporo cyanide. He kino te whakawhiti wera me te kawe hiko. Ko te Tellurium me te parakore neke atu i te 99.99% ka kiia ko te tellurium parakore teitei.
