1. [Whakataki]
Ko Tellurium he huānga quasi-metallic me te tohu Te. Ko Tellurium he karaihe hiriwa-ma o te raupapa rhombohedral, ka whakarewahia i roto i te waikawa sulfuric, te waikawa nitric, te aqua regia, te pāhare pāporo cyanide me te pāhare pāporo waihā, karekau i te wai matao me te wera me te waro disulfide. I whiwhi te tellurium parakore teitei ma te whakamahi i te paura tellurium hei rauemi mata me te tango me te whakamahine ki te konutai polysulfide. Ko te parakore ko 99.999%. Mo te taputapu semiconductor, nga koranu, nga matū matū me nga taapiri ahumahi penei i te rino, te rapa, te karaihe, me era atu.
2. [Natura]
E rua nga allotropy o Tellurium, ara, te paura pango, te tellurium amorphous me te ma hiriwa, te whiti konganuku, me te tellurium tioata hexagonal. Semiconductor, āputa ropu 0.34 ev.
O nga allotropy e rua o te tellurium, ko tetahi he tioata, he konganuku, he hiriwa-ma me te pakarukaru, he rite ki te antimony, ko tetahi he paura amorphous, he hina pouri. Kiato Waenga, iti rewa me te ira koropuke. He konganuku kore, engari he pai te kawe i te wera me te hiko. O ona hoa kore konganuku katoa, ko te tino whakarewa.
3. [Tono]
He momo hou o te rauemi infrared te purea teitei tellurium kotahi. Ko te tellurium tikanga ka taapirihia ki te rino me te koranu parahi hei whakapai ake i te machinability me te whakapiki ake i te pakeke; i roto i te rino ma, ka whakamahia te tellurium tikanga hei whakapumau carbide kia pakari ai te mata me te mau-atete; Ko te mata, he iti nei te tellurium, ka tapirihia ki te koranu hei whakapai ake i tona machinability me te whakanui ake i tona pakeke, ka whakapai ake i te parenga waikura o te rauemi, te mau atete me te kaha, a ka whakamahia hei kopaki mo nga taura o raro; Ko te taapiri i te tellurium ki te arahi ka piki ake te pakeke, ka whakamahia hei hanga pereti pākahiko me te momo momo. Ka taea te whakamahi Tellurium hei taapiri mo nga whakakorikori pakaru hinu me te whakakorikori mo te whakarite i te ethylene glycol. Ka whakamahia te waikura Tellurium hei karaehe. Ka taea te whakamahi i te tellurium parakore hei waahanga whakakotahi i roto i nga rauemi thermoelectric. Ko te Bismuth telluride he rauemi whakamatao pai. Ko Tellurium te Rarangi o nga rawa whakaahuru me te maha o nga pūhui telluride, penei i te cadmium telluride, i roto i nga pūtau solar.
I tenei wa, kei te whanake tere te ahumahi o te cdte kiriata angiangi o te hiko solar, e kiia ana ko tetahi o nga hangarau kaha o te ra.
