Muaj ib hom hlau uas yog qhov zoo nkauj heev. Hauv lub neej txhua hnub, nws tshwm hauv cov kua ua kua xws li mercury. Yog tias koj poob nws ntawm ib qho tuaj yeem, koj yuav xav tsis thoob uas pom tias lub raj mis yuav ua li tsis yooj yim li cov ntawv, thiab nws yuav tawg nrog kev chim xwb. Ib qho ntxiv, poob nws cov hlau me xws li tooj liab thiab hlau kuj tseem tuaj yeem hu ua "Hlau Trerminator". Dab tsi ua rau nws muaj cov yam ntxwv zoo li no? Niaj hnub no peb yuav nkag rau lub ntiaj teb ntawm gallium.
1, dab tsi yoggallium hlau
Gallium caij yog nyob rau hauv lub plaub ntu IIia pawg nyob rau hauv lub sij hawm lub sij hawm ntawm cov ntsiab lus. Qhov tseeb melting ntawm Gallium ntshiab yog tsawg heev, tsuas yog 29.78 ℃, tab sis qhov npau npau yog siab li 2204.8 ℃. Nyob rau lub caij ntuj sov, feem ntau ntawm nws muaj ua kua thiab tuaj yeem yaj thaum muab tso rau hauv xibtes. Los ntawm cov khoom tau saum toj no, peb tuaj yeem nkag siab tias gallium tuaj yeem colium lwm cov av me me vim hais tias ntawm nws qhov kev sib tw me me. Cov ntaub ntawv ua kua thoob plaws alloys nrog lwm cov hlau, uas yog qhov tshwm sim zoo txawv tau hais ua ntej. Nws cov ntsiab lus hauv lub ntiaj teb crust tsuas yog hais txog 0.001%, thiab nws cov hav zoov tsis tau pom txog li 140 xyoo dhau los. Xyoo 1871, Lavxias teb chaws Mendeleev Sumperized cov lus hauv qab no, uas muaj qhov zoo sib xws rau txhuas thiab yog hu ua "Aluminium xws li lub caij". Xyoo 1875, thaum Fabkis tus kws tshawb fawb Bowabordland tau kawm txog qhov kev coj noj coj ua ntawm cov khoom siv hluav taws xob ( hauv kev sim.
Gallium feem ntau muab faib rau hauv Suav teb, Tebchaws Yelemees, Fabkis, Tebchaws Australia, Yunnan, Yunnan, Henan, Guangxi thiab lwm qhov chaw [1]. Hais txog hom kev faib tawm, Shanxi, Shankxi, Shandong thiab lwm qhov chaw muaj nyob hauv Bin ore, thiab lwm qhov chaw nyob hauv sphaalerite. Thaum pib ntawm kev tshawb pom ntawm gallium hlau, vim tsis muaj kev tshawb fawb ntawm nws daim ntawv thov, tib neeg yeej ib txwm ntseeg tias nws yog hlau nrog cov khoom siv tsawg. Txawm li cas los xij, nrog kev txhim kho cov ntaub ntawv txuas ntxiv thiab cov era ntawm cov khoom siv tshiab thiab cov khoom tseem ceeb hauv cov ntaub ntawv teb, thiab nws cov kev thov tau nce ntau ntxiv.
2, daim ntawv teev nrog rau cov hlau gallium
1. Semiconductor teb
Gallium yog tsuas yog siv nyob rau hauv cov ntaub ntawv ntawm cov ntaub ntawv semiconductor, nrog gallium arsenide (gaas) ua cov siv ntau tshaj plaws thiab thev naus laus zis yog qhov paub tab tshaj plaws. Raws li cov ntaub ntawv tshaj tawm cov ntaub ntawv tshaj tawm, cov ntaub ntawv semiconductor account rau 80% rau 85% ntawm kev sib txuas lus tag nrho ntawm gallium, feem ntau yog siv hauv kev sib txuas lus wireless. Gallium arsenide lub zog amplifiiers tuaj yeem ua kom muaj kev sib txuas lus ntxiv kom 100 npaug ntawm 4G tes haujlwm, uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev nkag mus rau 5G era. Ntxiv mus, gallium tuaj yeem siv los ua tshav kub dissipation nruab nrab yog nws cov yam ntxwv thermal, siab thermal conductivity, thiab kev txaus ntws zoo. Ua ntawv thov cov hlau hauv daim ntawv ntawm gallium raws li cov khoom siv hluav taws xob tuaj yeem txhim kho lub peev xwm ua kom sov thiab ua haujlwm hauv hluav taws xob.
2. Hnub ci hlwb
Kev txhim kho ntawm lub hnub ci hlwb tau ploj mus ntawm thaum ntxov Monocrystalline Silicon Hnub ci hlwb rau polycrystalline silicon nyias zaj duab xis hlwb. Vim yog tus nqi siab ntawm polycrystalline silicon nyias zaj duab xis hlwb, zaj duab xis tau ua yeeb yaj kiab tseem ceeb (yeeb) cov ntaub ntawv hauv cov ntaub ntawv [3]. CIGPS cov cells muaj qhov zoo ntawm cov nqi ntau lawm, loj pob ntau lawm, thiab muaj kev sib hloov siab loj, yog li muaj kev txhim kho dav cia cov zeem muag. Thib ob, Gallium arsenide solar hlwb muaj qhov tseem ceeb hauv kev hloov ua tau zoo piv rau cov yeeb yaj kiab nyias ua los ntawm lwm cov ntaub ntawv. Txawm li cas los xij, vim muaj cov nqi tsim muaj ntau ntawm GALSEAL cov ntaub ntawv, lawv yog tam sim no siv nyob rau hauv Aerospace thiab cov tub rog teb.
3. Hydrogen Zog
Nrog rau kev paub ntxiv ntawm lub zog teeb meem thoob plaws ntiaj teb, tib neeg tab tom nrhiav kev hloov kho lub zog tsis siv hluav taws xob ntxiv. Txawm li cas los xij, tus nqi siab thiab tsawg kev nyab xeeb ntawm hydrogen cia thiab tsheb thauj mus los tab rau kev txhim kho ntawm cov thev naus laus zis no. Raws li cov khoom siv ntau tshaj plaws hauv lub cev tawv nqaij muaj cov tshuaj tiv thaiv hydrogen hauv qab, uas yog qhov tshuaj tiv thaiv hydrogen nyob rau hauv cov tshuaj tiv thaiv kab mob hlau tau rov siv dua tshiab thiab rov siv dua. Kev siv ntawm txhuas gallium alloy cov ntaub ntawv zoo heev daws thiab kev thauj khoom ntawm hydrogen zog, txhim kho kev nyab xeeb, kev lag luam, thiab kev tiv thaiv kev muaj cai, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig.
4. Kho Mob Teb
GALLIIs yog feem ntau siv nyob rau hauv kev kho mob kev kho mob vim nws cov khoom siv hluav taws xob, uas tuaj yeem siv rau kev xav thiab inhibiting cov qog ua qog. Gallium cov tebchaw muaj cov tshuaj tiv thaiv kab mob uas pom tau cov tshuaj tiv thaiv kab mob antifungal thiab cov tshuaj tua kab mob, thiab thaum kawg ua tiav cov kab mob meterary nrog cov meterabolism. Thiab gallium alloys tuaj yeem siv los ua cov ntsuas kub, xws li cov pa hluav taws xob tin, thiab muaj peev xwm siv los hloov cov tshuaj lom neeg mercury. Tsis tas li ntawd, qee qhov ntsuas ua feem ntawm gallium raws li cov nyiaj tsoos ib txwm muaj amalgam thiab siv nyob rau hauv cov ntawv thov kev kho mob tshiab ua cov khoom siv smoot kws kho hniav tshiab.
3, Outlook
Txawm hais tias Tuam Tshoj yog ib qho ntawm cov neeg tsim khoom loj hauv gallium nyob hauv lub ntiaj teb, tseem muaj ntau yam teeb meem nyob hauv Suav teb gallium kev lag luam. Vim tias cov ntsiab lus tsawg ntawm galium ua cov lag luam ntxhia, galalital steparrises yog tawg, thiab muaj cov kev txuas tsis muaj zog hauv txoj saw muaj. Cov txheej txheem mining muaj qhov muaj kuab paug ib puag ncig, thiab ntau zog ntawm gallium gallium ntawm tus nqi sib xyaw tsawg ntawm gallium ntawm cov nqi siab. Txawm li cas los xij, nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, kev txhim kho ntawm cov neeg muaj txoj sia nyob hauv cov ntaub ntawv thiab lub zog, qhov kev thov yuav nce siab. Qhov txuas ntxiv rov qab ntau lawm tshuab ntawm kev siab-purity gallium yuav inevitably muaj kev txwv ntawm Tuam Tshoj txoj kev lag luam kev tsim kho. Kev tsim cov thev naus laus zis tshiab yog qhov tseem ceeb tshaj plaws rau kev ua tiav cov kev tsim txiaj zoo ntawm kev tshawb fawb thiab thev naus laus zis hauv Suav teb.
