Qhov sib txawv tseem ceeb ntawm titanium oxide thiab titanium dioxide yog tias titanium oxide muaj ib qho oxygen anion rau ib titanium cation whereas titanium dioxide muaj ob oxygen anions ib titanium cation.
Titanium yog cov khoom siv tshuaj lom neeg muaj cov cim tshuaj Ti thiab tus lej atomic 22. Nws yog cov hlau nplaum uas poob rau hauv qeb ntawm cov hlau hloov pauv. Raws li tus yam ntxwv tseem ceeb, nws muaj lub zog siab piv rau nws qhov ntom ntom. Cov khoom no tuaj yeem muaj ntau lub xeev oxidation, tab sis qhov ruaj khov oxidation lub xeev yog +4. Muaj ob peb oxides nws tuaj yeem tsim xws li titanium (II) oxide, titanium (III) oxide thiab titanium dioxide.
Titanium Oxide yog dab tsi?
Titanium oxide yog ib qho inorganic compound uas muaj cov tshuaj formula TiO. Peb lub npe no yog titanium monoxide lossis titanium (II) oxide. Cov molar mass ntawm no compound yog 63.87 g / mol. Nws zoo li bronze crystals. Ntxiv mus, nws muaj lub siab melting point uas yog 1, 750 ° C, thiab qhov ceev yog 4.95 g / cm3Thaum xav txog cov qauv siv lead ua ntawm cov khoom sib xyaw no, nws muaj cov qauv cubic.
Peb tuaj yeem npaj cov tshuaj no los ntawm titanium dioxide lossis los ntawm titanium hlau thiab. Tab sis peb yuav tsum ua qhov no tshwm sim ntawm 1500 ° C. Tsis tas li ntawd, cov kua qaub ntawm cov tshuaj no ruaj khov rau lub sijhawm luv luv, tab sis tom qab ntawd nws yuav decompose kom muab hydrogen. Cov tshuaj tiv thaiv no yog raws li nram no:
2Ti2+(aq) + 2H+(aq) → 2Ti3+ (aq) + H2(g)
Titanium Dioxide yog dab tsi?
Titanium dioxide yog ib qho inorganic compound uas muaj cov tshuaj formula TiO2Qhov no yog qhov tshwm sim oxide ntawm titanium. Ntxiv mus, peb lub npe no compound li titanium (IV) oxide. Cov molar mass ntawm no compound yog 79.87 g / mol. Nws zoo nkaus li cov khoom dawb. Nws muaj qhov siab melting point yog 1,843 ° C. Qhov ntom ntawm qhov sib xyaw no txawv raws li hom qauv siv lead ua uas nws muaj. Piv txwv li, qhov ceev ntawm rutile siv lead ua qauv yog 4.23 g / cm3thaum qhov ceev ntawm cov qauv siv lead ua anatase yog 3.78 g / cm3
Daim duab 01: Titanium Dioxide Dawb Khoom
Peb tuaj yeem tsim cov khoom sib xyaw no los ntawm kev ua cov titanium bearing xuab zeb xws li ilmenite ntxhia xuab zeb. Thaum xav txog cov kev siv loj ntawm cov khoom sib xyaw no, nws suav nrog kev tsim cov titanium dioxide pigments uas tseem ceeb rau kev tsim cov xim, ntawv, yas, thiab lwm yam.
Qhov txawv ntawm Titanium Oxide thiab Titanium Dioxide yog dab tsi?
Titanium oxide yog ib qho inorganic compound uas muaj cov tshuaj formula TiO whereas titanium dioxide yog ib qho inorganic compound uas muaj cov tshuaj formula TiO2 Yog li, titanium oxide muaj ib qho oxygen anion rau ib qho. titanium cation tab sis, titanium dioxide muaj ob lub pa oxygen rau ib titanium cation. Qhov no yog qhov sib txawv tseem ceeb ntawm titanium oxide thiab titanium dioxide. Tsis tas li ntawd, vim cov qauv no, lawv muaj cov molar sib txawv thiab cov ntsiab lus melting sib txawv. Ntxiv mus, oxidation tus naj npawb ntawm titanium nyob rau hauv txhua qhov sib txawv ntawm ib leeg; Tus lej oxidation ntawm titanium hauv titanium oxide yog +2 thaum oxidation tooj ntawm titanium hauv titanium dioxide yog +4. Qhov no yog lwm qhov sib txawv tseem ceeb ntawm titanium oxide thiab titanium dioxide.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm titanium oxide thiab titanium dioxide kom ntxaws.
Summary – Titanium Oxide vs Titanium Dioxide
Titanium oxide thiab titanium dioxide yog cov oxides tseem ceeb ntawm titanium tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm titanium oxide thiab titanium dioxide yog tias titanium oxide muaj ib qho oxygen anion rau ib titanium cation tab sis, titanium dioxide muaj ob qho oxygen anions ib titanium cation.
