Qhov sib txawv tseem ceeb ntawm titanium thiab platinum yog tias platinum tsis oxidize ntawm qhov kub thiab txias, whereas titanium oxidizes thiab tsim titanium dioxide.
Ob leeg titanium thiab platinum yog d thaiv cov ntsiab lus. Lawv feem ntau hu ua cov hlau hloov pauv. Zoo li feem ntau ntawm cov hlau hloov pauv, cov no kuj muaj peev xwm tsim cov tebchaw nrog ntau lub xeev oxidation thiab tuaj yeem tsim cov complexes nrog ntau yam ligands. Txawm li cas los xij, vim tias ob qho tib si hlau yog kim heev, uas txwv lawv cov kev siv.
Y Titanium yog dab tsi?
Titanium yog cov khoom siv tshuaj nrog tus lej atomic 22 thiab lub cim Ti. Nws yog ib qho d thaiv cov ntsiab lus thiab tam sim no nyob rau hauv lub sij hawm thib 4 ntawm lub sij hawm lub sij hawm. Electron configuration ntawm lub caij no yog 1s2 2s2 2p6 3s2 3p6 4s2 3d2 Ntxiv mus, nws nyiam kev sib xyaw nrog +4 oxidation xeev. Tab sis nws tuaj yeem muaj +3 lub xeev oxidation.
Atomic huab hwm coj ntawm cov khoom no yog kwv yees li 48 g mol-1 Nws yog cov hlau hloov pauv nrog cov xim ci ci. Tsis tas li ntawd, nws muaj zog tab sis muaj qhov ntom ntom, kuj corrosion resistant thiab ruaj. Nws kuj tseem muaj qhov melting point ntau dua ntawm 1668 o C. Titanium yog paramagnetic thiab muaj hluav taws xob tsawg thiab thermal conductivity. Muaj cov hlau ntshiab yog tsis tshua muaj vim nws yog reactive nrog oxygen. Nyob ntawd, nws tuaj yeem tsim titanium oxide thaum ua haujlwm nrog oxygen. Yog li, txheej txheej titanium dioxide no ua raws li cov txheej txheem tiv thaiv ntawm cov hlau no thiab tiv thaiv nws los ntawm corrosion. Titanium dioxide muaj txiaj ntsig zoo hauv cov ntawv, xim thiab kev lag luam yas. Txawm hais tias titanium hlau yog soluble nyob rau hauv concentrated acids, nws yog non-reactive nrog dilute inorganic thiab organic acids.
Daim duab 01: Ti npib
Ntxiv mus, vim nws cov khoom, titanium yog qhov tseem ceeb hauv ntau daim ntawv thov. Txij li nws tsis corrode yooj yim los ntawm dej hiav txwv, peb tuaj yeem siv nws los ua cov khoom hauv nkoj. Tsis tas li ntawd, lub zog thiab lub teeb yuag tso cai rau titanium siv dav hlau, foob pob ua ntxaij, cuaj luaj, thiab lwm yam. Tsis tas li ntawd, cov hlau no tsis muaj tshuaj lom thiab biocompatible, ua rau nws haum rau biomaterial daim ntaub ntawv. titanium yog cov hlau muaj txiaj ntsig. Yog li ntawd tib neeg siv nws los ua cov hniav nyiaj hniav kub ib yam nkaus.
Platinum yog dab tsi?
Platinum lossis Pt yog cov hlau hloov pauv nrog tus lej atomic 78. Nws yog nyob rau hauv tib lub sijhawm pawg pawg xws li npib tsib xee thiab palladium. Yog li ntawd, nws muaj lub teeb tsa hluav taws xob zoo ib yam li npib tsib xee nrog cov txheej txheem sab nrauv uas muaj s 2 d 8 kev npaj. Tsis tas li, cov hlau no feem ntau ua rau +2 thiab +4 oxidation xeev. Txawm li cas los xij, nws tuaj yeem tsim +1 thiab +3 oxidation xeev ib yam nkaus.
Ntxiv mus, platinum yog silvery dawb thiab muaj qhov ceev dua. Atomic loj ntawm nws yog hais txog 195 g mol-1 Nws tsis oxidize los yog reacts nrog HCl los yog nitric acid. Tsis tas li ntawd, nws yog heev resistant rau corrosion. Tsis tas li ntawd, nws tuaj yeem tiv taus kub heev yam tsis muaj melting. (Nws lub ntsiab lus melting yog 1768.3 ° C).
Daim duab 02: Pt Jewellery
Dhau li ntawm, platinum yog paramagnetic. Tsis tas li ntawd, nws yog ib qho hlau tsis tshua muaj, uas peb siv hauv kev tsim cov hniav nyiaj hniav kub. Platinum jewelery yog kim heev. Tsis tas li ntawd, peb tuaj yeem siv cov hlau no ua cov electrode hauv electrochemical sensors, thiab hlwb. Nws yog ib qho zoo catalyst siv nyob rau hauv cov tshuaj tiv thaiv. South Africa yog tus naj npawb ib tus tsim cov platinum hlau.
Qhov txawv ntawm Titanium thiab Platinum yog dab tsi?
Titanium yog cov khoom siv tshuaj nrog tus lej atomic 22, thiab lub cim Ti thiab Platinum lossis Pt yog cov hlau hloov pauv nrog tus lej atomic 78. Qhov sib txawv tseem ceeb ntawm titanium thiab platinum yog platinum tsis oxidize ntawm ib qho twg. Qhov kub, qhov titanium oxidizes thiab tsim titanium dioxide.
Ntxiv mus, platinum yog denser dua titanium. Txawm li cas los xij, titanium nyuaj dua platinum. Raws li cov khoom, qhov no yog qhov sib txawv tseem ceeb ntawm titanium thiab platinum. Raws li lwm qhov sib txawv ntawm titanium thiab platinum, platinum yog tsawg heev, ua rau nws kim dua titanium.
Summary – Titanium vs Platinum
Titanium thiab platinum yog d thaiv cov ntsiab lus, thiab peb tuaj yeem categorize lawv li hlau. Qhov sib txawv tseem ceeb ntawm titanium thiab platinum yog tias platinum tsis oxidize ntawm qhov kub thiab txias, whereas titanium oxidizes thiab tsim titanium dioxide.
