Nā Pae ʻEpekema Kaulana|i loko o ke Ao o Tellurium

1. [Hoʻolauna]
He mea quasi-metallic ka Tellurium me ka hōʻailona Te. He kristal kālā-keʻokeʻo ka Tellurium o ka moʻo rhombohedral, hiki ke hoʻoheheʻe ʻia i loko o ka waikawa sulfuric, ka waikawa nitric, aqua regia, potassium cyanide a me ka potassium hydroxide, hiki ʻole ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela a me ke kalapona disulfide. Ua loaʻa ka tellurium maʻemaʻe kiʻekiʻe ma 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 ka maʻemaʻe he 99.999%. No nā mea semiconductor, nā alloys, nā mea maka kemika a me nā mea hoʻohui ʻoihana e like me ka hao i hoʻolei ʻia, ka rubber, ke aniani, a pēlā aku.

ʻElua allotropy o ka Tellurium, ʻo ia hoʻi, ka pauka ʻeleʻele, ka tellurium amorphous a me ke keʻokeʻo kālā, ka luster metala, a me ka tellurium crystalline hexagonal. Semiconductor, bandgap 0.34 ev.
ʻO nā ʻano ʻelua o ka tellurium, ʻo kekahi he crystalline, metallic, silvery-white a brittle, like me ka antimony, a ʻo kekahi he pauka amorphous, hina ʻeleʻele. Waena ka nui, haʻahaʻa ka heheʻe ʻana a me ka paila ʻana. He mea ʻole ia he metala, akā alakaʻi maikaʻi loa ia i ka wela a me ka uila. ʻO kona mau hoa ʻole-metala a pau, ʻo ia ka mea metallic loa.

ʻO ke aniani hoʻokahi tellurium maʻemaʻe kiʻekiʻe he ʻano mea infrared hou. Hoʻohui ʻia ka tellurium maʻemaʻe kiʻekiʻe i nā mea hao kila a me ke keleawe e hoʻomaikaʻi i ko lākou mīkini a hoʻonui i ka paʻakikī; i loko o ka hao hoʻolei keʻokeʻo, hoʻohana ʻia ka tellurium maʻamau ma ke ʻano he mea hoʻopaʻa carbide e hana i ka ʻili paʻakikī a kūpaʻa i ke komo ʻana; ʻo ke kēpau, nona ka liʻiliʻi o ka tellurium, hoʻohui ʻia i ka mea hao e hoʻomaikaʻi i kona mīkini a hoʻonui i kona paʻakikī, hoʻomaikaʻi ia i ke kūpaʻa ʻana o ka mea i ka palaho, ke kūpaʻa ʻana a me ka ikaika, a hoʻohana ʻia ma ke ʻano he ʻōpala no nā kaula submarine; ʻo ka hoʻohui ʻana i ka tellurium i ke kēpau e hoʻonui i kona paʻakikī, a hoʻohana ʻia e hana i nā papa pākahiko a me ke ʻano. Hiki ke hoʻohana ʻia ka Tellurium ma ke ʻano he mea hoʻohui no nā mea hoʻouluulu haki petroleum a ma ke ʻano he mea hoʻouluulu no ka hoʻomākaukau ʻana o ka ethylene glycol. Hoʻohana ʻia ka Tellurium oxide ma ke ʻano he kala i loko o ke aniani. Hiki ke hoʻohana ʻia ka tellurium maʻemaʻe kiʻekiʻe ma ke ʻano he ʻāpana hoʻohui i nā mea thermoelectric. He mea hoʻomaʻalili maikaʻi ʻo Bismuth telluride. ʻO Tellurium ka papa inoa o nā mea semiconductor me kekahi mau hui telluride, e like me ka cadmium telluride, i loko o nā cell solar.
I kēia manawa, ke ulu wikiwiki nei ka ʻoihana o ka ikehu lā ʻili lahilahi cdte, kahi i manaʻo ʻia ʻo ia kekahi o nā ʻenehana ikehu lā hoʻohiki nui loa.
