Dab tsi yog qhov txheeb ze atomic mass ntawm titanium?
Nyob rau hauv lub ntiaj teb microscopic ntawm chemistry, cov ntsiab lus zoo li cov hnub qub, txhua tus muaj nws tus kheej cim thiab cov khoom. Ntawm lawv, titanium, raws li lub teeb yuag, corrosion-resistant, high-strength hlau, yog dav siv nyob rau hauv aerospace, kev kho mob, tshuaj thiab lwm yam teb. Txawm li cas los xij, koj puas tau xav paub txog qhov txheeb ze atomic loj ntawm cov hlau tej yam yees siv, titanium? Niaj hnub no, cia peb nthuav tawm qhov paub tsis meej ntawm titanium thiab tshawb nrhiav qhov tsis meej ntawm nws cov txheeb ze atomic loj.
1. txheeb ze atomic mass ntawm titanium
Cov txheeb ze atomic mass yog ib qho tseem ceeb ntawm lub cev muaj nuj nqis hauv chemistry. Nws sawv cev rau qhov piv ntawm atomic mass ntawm ib lub caij mus rau 1/12 ntawm atomic mass ntawm carbon-12. Tom qab kev ntsuas tseeb los ntawm cov kws tshawb fawb, nws cov txheeb ze atomic loj yog li 47.87. Qhov no zoo li tus lej yooj yim tiag tiag muaj cov yam ntxwv tseem ceeb ntawm qhov loj ntawm titanium atoms thiab yog qhov tseem ceeb rau kev nkag siab thiab siv lub caij titanium. Nws yog nrog cov ntaub ntawv meej no uas peb tuaj yeem nkag siab zoo dua cov khoom thiab kev siv titanium thiab pab txhawb rau kev tshawb fawb thiab thev naus laus zis ntawm noob neej.
2. Titanium isotopes
Tus txheeb ze atomic loj ntawm titanium tsis yog tus nqi ruaj khov, tab sis nws txawv raws li cov isotopes sib txawv ntawm titanium. Isotopes hais txog cov atoms sib txawv ntawm tib lub caij nrog tib tus naj npawb ntawm protons tab sis sib txawv ntawm cov neutrons. Titanium isotopes suav nrog Ti-46, Ti-47, Ti-48, thiab lwm yam, thiab lawv cov txheeb ze atomic masses yog 45.95, 46.94 thiab 47.95 raws li. Cov isotopes tau muab faib ua ntau qhov sib txawv hauv qhov xwm txheej, uas cuam tshuam rau tag nrho cov txheeb ze atomic loj ntawm titanium.
3. Daim ntawv thov ntawm titanium
Vim lub me me txheeb ze atomic loj ntawm titanium thiab nws cov compact atomic qauv, titanium muaj zog heev thiab hardness. Titanium yog li 40% sib zog dua hlau, tab sis nws lub zog yog piv rau cov hlau! Nyob rau tib lub sijhawm, qhov ntom ntawm titanium kuj me me, nrog qhov ntom ntawm 4.51 g / cm3, uas ua rau nws yog ib qho khoom siv zoo tagnrho. Nyob rau hauv lub tshav pob ntawm aerospace, titanium yog dav siv nyob rau hauv kev tsim cov plhaub thiab cov yam ntxwv ntawm lub dav hlau xws li aircraft thiab foob pob ua ntxaij, zoo heev txo qhov loj ntawm spacecraft thiab txhim kho nws cov kev ua tau zoo ntawm lub davhlau.
4. Txoj kev rho tawm ntawm titanium
Titanium muaj ntau heev nyob rau hauv lub ntiaj teb crust, tab sis nws yog ib qho nyuaj rau rho tawm ncaj qha los ntawm cov ore vim nws active tshuaj zog. Tam sim no, kev lag luam feem ntau siv Claus txoj kev los yog molten ntsev electrolysis txoj kev los npaj titanium hlau. Txawm hais tias cov txheej txheem no nyuaj thiab raug nqi, nws yog cov kev siv zog uas tau ua titanium, cov hlau zoo nkauj, dav siv hauv ntau yam.
Txawm hais tias tus txheeb ze atomic loj ntawm titanium tsuas yog tus lej yooj yim xwb, nws muaj cov yam ntxwv tseem ceeb ntawm qhov zoo ntawm titanium thiab muaj peev xwm ntawm daim ntawv thov dav. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev lag luam ntawm titanium kuj tseem nthuav dav. Los ntawm ib txwm aerospace thiab biomedical teb mus rau lub zog tshiab thiab kev tiv thaiv ib puag ncig, titanium tau pom muaj peev xwm thiab muaj txiaj ntsig zoo. Nyob rau yav tom ntej, peb muaj laj thawj ntseeg tias titanium tseem yuav ua lub luag haujlwm tseem ceeb hauv theem ntawm chemistry thiab cov ntaub ntawv tshawb fawb.
