Ka unuhi oGalium
Galiumme he ʻāpana tin i ka lumi wela, a inā makemake ʻoe e paʻa i loko o kou poho lima, hehee koke ia i loko o nā lei kālā.Ma mua, haʻahaʻa loa ka helu heheʻe o ka galium, 29.8C wale nō.ʻOiai he haʻahaʻa loa ka helu hoʻoheheʻe o ka galium, he kiʻekiʻe loa kona wahi e hoʻolapalapa ai, a hiki i ka 2070C.Hoʻohana nā kānaka i nā waiwai o ka gallium e hana i nā thermometers no ke ana ʻana i nā wela kiʻekiʻe.Hoʻokomo ʻia kēia mau ana wela i loko o ka umu ahi hana kila, a ua aneane hehee ka pūpū aniani.ʻAʻole i paila ka galium i loko.Inā hoʻohana ʻia ke aniani quartz kiʻekiʻe e hana i ka pūpū o kahi thermometer gallium, hiki iā ia ke ana mau i kahi wela kiʻekiʻe o 1500C.No laila, hoʻohana pinepine ka poʻe i kēia ʻano thermometer e ana i ka mahana o nā umu ahi a me nā reactors atomic.
Loaʻa i ka Gallium nā waiwai hoʻolei maikaʻi, a ma muli o kāna "hōʻemi wela a me ka hoʻonui ʻana i ke anuanu", hoʻohana ʻia ia e hana i nā alloys alakaʻi, e hoʻomaʻamaʻa i ka font.I ka ʻoihana ikehu atomic, hoʻohana ʻia ka gallium ma ke ʻano he mea hoʻololi wela e hoʻoneʻe i ka wela mai nā reactors.ʻO Gallium a me nā metala he nui, e like me ka bismuth, ke kēpau, tin, cadmium, a me nā mea ʻē aʻe, e hana i ka alloy fusible me kahi helu heheʻe ma lalo o 60C.Ma waena o lākou, hiki ke hoʻohana ʻia ka gallium steel alloy me 25% (melting point 16C) a me ka gallium tin alloy i loaʻa ka 8% tin (melting point 20C) i nā fuse kaapuni a me nā mea palekana like ʻole.Ke kiʻekiʻe ka mahana, e hoʻoheheʻe koke lākou a hemo, e pāʻani ana i kahi hana palekana.
Ma ka launa pū ʻana me ke aniani, loaʻa iā ia ka hopena o ka hoʻonui ʻana i ka index refractive o ke aniani a hiki ke hoʻohana ʻia no ka hana ʻana i ke aniani optical kūikawā.No ka mea he ikaika loa ka gallium e hoʻomālamalama i ka mālamalama a hiki ke pili pono i ke aniani, me ka pale ʻana i nā wela kiʻekiʻe, kūpono loa ia no ka hoʻohana ʻana ma ke ʻano he mea hoʻomālamalama.Hiki i nā aniani Gallium ke hoʻomanaʻo i hope ma mua o 70% o ka mālamalama i hoʻokuʻu ʻia.
ʻO kekahi mau pūhui o ka gallium i kēia manawa ua paʻa ʻole i ka ʻepekema a me ka ʻenehana.ʻO Gallium arsenide kahi mea semiconductor hou i ʻike ʻia me ka hana maikaʻi loa i nā makahiki i hala.ʻO ka hoʻohana ʻana iā ia ma ke ʻano he mea uila hiki ke hōʻemi nui i ka nui o nā mea uila a hoʻokō i ka miniaturization.Ua hana pū ka poʻe i nā lasers me ka hoʻohana ʻana i ka gallium arsenide ma ke ʻano he ʻāpana, ʻo ia kahi ʻano laser hou me ka hana kiʻekiʻe a me ka liʻiliʻi liʻiliʻi.ʻO Gallium a me nā pūhui phosphorus - ʻO Gallium phosphide kahi mea hoʻoheheʻe kukui semiconductor hiki ke hoʻokuʻu i ke kukui ʻulaʻula a i ʻole ka ʻōmaʻomaʻo.Ua hana ʻia i loko o nā ʻano helu Arab like ʻole a hoʻohana ʻia i nā kamepiula uila e hōʻike i nā hopena helu.
