Kaulana ʻepekema Horizons|i loko o ke ao o Tellurium

1. [Hoʻolauna]
ʻO Tellurium kahi mea quasi-metallic me ka hōʻailona Te. ʻO Tellurium kahi aniani keʻokeʻo kālā o ka rhombohedral series, hiki ke hoʻoheheʻe ʻia i ka sulfuric acid, nitric acid, aqua regia, potassium cyanide and potassium hydroxide, insoluble i ke anuanu a me ka wai wela a me ka carbon disulfide. Loaʻa ka tellurium maʻemaʻe kiʻekiʻe ma o ka hoʻohana ʻana i ka pauka tellurium ma ke ʻano he mea maka a me ka unuhi ʻana a me ka hoʻomaʻemaʻe ʻana me ka sodium polysulfide. ʻO 99.999% ka maʻemaʻe. No nā mea semiconductor, nā mea hoʻoheheʻe, nā mea kemika a me nā mea hoʻohui ʻoihana e like me ka hao hao, ka hao, ke aniani, etc.

He ʻelua alotropy ʻo Tellurium, ʻo ia hoʻi, ka pauka ʻeleʻele, ka tellurium amorphous a me ke keʻokeʻo keʻokeʻo, ka luster metala, a me ka tellurium crystalline hexagonal. Semiconductor, bandgap 0.34 ev.
ʻO nā allotropy ʻelua o tellurium, ʻo kekahi he crystalline, metala, keʻokeʻo keʻokeʻo a me ka brittle, e like me ka antimony, a ʻo kekahi he pauda amorphous, ʻeleʻele hina. Medium density, haʻahaʻa heheʻe a me ka paila. He mea hao ʻole ia, akā hoʻokele maikaʻi loa ia i ka wela a me ka uila. ʻO kona mau hoa pili ʻole a pau, ʻo ia ka mea hao loa.

ʻO ke kiʻekiʻe maʻemaʻe tellurium hoʻokahi kristal he ʻano hou o nā mea infrared. Hoʻohui ʻia ka tellurium maʻamau i ke kila a me ke keleawe e hoʻomaikaʻi ai i kā lākou machinability a hoʻonui i ka paʻakikī; i ka hao keʻokeʻo, hoʻohana ʻia ka tellurium maʻamau ma ke ʻano he carbide stabilizer e hoʻoikaika i ka ʻili a paʻakikī; ʻO ke alakaʻi, kahi i loko o ka tellurium liʻiliʻi, ua hoʻohui ʻia i ka huila e hoʻomaikaʻi i kona machinability a hoʻonui i kona paʻakikī, hoʻomaikaʻi ia i ka pale ʻana i ka corrosion o ka mea, hoʻohana i ke kūpaʻa a me ka ikaika, a hoʻohana ʻia e like me ka puʻu no nā kaula submarine; ʻO ka hoʻohui ʻana i ka tellurium i ke alakaʻi e hoʻonui i kona paʻakikī, a hoʻohana ʻia e hana i nā pā pākaukau a me ke ʻano. Hiki ke hoʻohana ʻia ʻo Tellurium ma ke ʻano he mea hoʻohui no nā catalysts cracking petroleum a ma ke ʻano he catalyst no ka hoʻomākaukau ʻana i ka ethylene glycol. Hoʻohana ʻia ka Tellurium oxide ma ke ʻano he kala i ke aniani. Hiki ke hoʻohana ʻia ka tellurium maʻemaʻe kiʻekiʻe ma ke ʻano he mea hoʻohui i nā mea thermoelectric. ʻO Bismuth telluride kahi mea hoʻoheheʻe maikaʻi. ʻO Tellurium ka papa inoa o nā mea semiconductor me kekahi mau pūhui telluride, e like me ka cadmium telluride, i loko o nā pūnaewele lā.
I kēia manawa, ke ulu wikiwiki nei ka ʻoihana o cdte thin film solar energy, i manaʻo ʻia ʻo ia kekahi o nā ʻenehana ikehu lā.
