Nā Mea Alakaʻi Hana Kiʻekiʻe--Kelepa Tellurium
Nā ʻano huahana o ke keleawe tellurium
ʻO ke keleawe Tellurium kahi mea hoʻohuihui i hana ʻia ma ka hoʻohui ʻana i kahi mea trace tellurium ma ke kumu o ke keleawe maʻemaʻe. ʻO ka hoʻohui ʻana o ka tellurium e hoʻomaikaʻi nui i ka hana ʻoki o ka mea, me ka mālama ʻana i ka conductivity uila a me ka thermal maikaʻi loa o ke keleawe. ʻOi aku ka conductivity o ke keleawe telluride ma mua o 90%IACS a me ka conductivity thermal ma mua o 350W/m·K, ka mea e lilo ai ia i mea kūpono no ka hana ʻana i nā ʻāpana uila pololei.
Ma ke ʻano o nā waiwai mechanical, hōʻike ka keleawe tellurium i ka ikaika a me ka paʻakikī maikaʻi loa.
Hiki i kona ikaika tensile ke piʻi aku ma mua o 300MPa a hiki i ka paʻakikī ke hiki i 80HB, ʻoi aku ka maikaʻi ma mua o nā mea keleawe maʻemaʻe maʻamau. I ka manawa like, loaʻa i ke keleawe tellurium ke kūpaʻa maikaʻi i ka ʻaʻahu a me ke kūpaʻa luhi, hiki ke hoʻokō i nā koi o ka hoʻohana lōʻihi.
ʻOi aku ka maikaʻi o ke keleawe tellurium i nā waiwai hana. Hiki i kāna helu hana ʻoki ke piʻi aʻe ma mua o 80%, ʻoi aku ka kiʻekiʻe ma mua o nā mea hao keleawe maʻamau. Hoʻomaikaʻi nui kēia hiʻohiʻona i ka pono hana a hoʻemi i ke kumukūʻai hana. Eia kekahi, loaʻa i ke keleawe tellurium nā waiwai hoʻoheheʻe maikaʻi a me nā waiwai mālama ʻili, kahi kūpono no ka hana ʻana ma hope.
Nā ʻano loea o ke keleawe tellurium
ʻO ke ʻano kemika maʻamau o ke keleawe tellurium e komo pū ana me: ka nui o ke keleawe ≥99.5%, ka nui o ka tellurium 0.4-0.7%, a ʻo ke koena he mau mea trace. ʻO kēia lakio hoʻonohonoho pololei e hōʻoiaʻiʻo i ke kūpaʻa a me ke kūlike o nā waiwai o nā mea.
Ma ke ʻano o nā waiwai kino, ʻo ka nui o ke keleawe tellurium he 8.9g/cm³, ʻo ke kiko heheʻe he 1083 ℃, a ʻo ke koina o ka hoʻonui wela he 17.0 × 10⁻⁶/℃. Hoʻoholo kēia mau palena i kona kūpaʻa a me ka hilinaʻi i nā wahi mahana kiʻekiʻe.
Hōʻike nā ʻano waiwai mechanical ʻo ka ikaika hua o ke keleawe tellurium he ≥200MPa a ʻo ka elongation he ≥15%, ka mea e hōʻoiaʻiʻo ai i ka palekana a me ke kūpaʻa o ka mea i ka wā e hoʻohana ai.
Ka hoʻohana ʻana o ke keleawe tellurium
I ka ʻoihana uila a me ka uila, hoʻohana nui ʻia ke keleawe tellurium i nā mea hoʻohui, nā relay, nā kuapo a me nā ʻāpana koʻikoʻi ʻē aʻe. ʻO kona conductivity uila maikaʻi loa a me nā waiwai hana e hōʻoiaʻiʻo i ka hilinaʻi a me ke kūpaʻa o nā lako uila.
I ka ʻoihana kaʻa, hoʻohana ʻia ke keleawe tellurium e hana i nā ʻāpana e like me nā sensor, nā kikowaena, a me nā fuses. ʻO kona kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ʻana i ka pala e hoʻokō i nā koi o ke kaiapuni hana ʻino o ke kaʻa.
Ma ka ʻoihana aerospace, ʻo ka ikaika kiʻekiʻe o ke keleawe tellurium a me nā waiwai conductive kiʻekiʻe e hoʻolilo iā ia i mea koho no ka hana ʻana i nā mea hana pololei a me nā mea uila. ʻO kona hilinaʻi a me kona kūpaʻa e hōʻoiaʻiʻo i ka hana palekana o nā lako aerospace.
He kuleana koʻikoʻi ko ke keleawe tellurium i ka ʻoihana hou ma muli o kona mau waiwai piha maikaʻi loa. Me ka holomua o ka ʻenehana, e hoʻomau ka hoʻonui ʻana o ke kahua noi o ke keleawe tellurium, e hāʻawi ana i ke kākoʻo waiwai ikaika no ka hoʻomohala ʻana o nā ʻoihana like ʻole.
