Physical thiab Chemical Properties | Dawb hmoov. Cov hmoov dawb nrog cov mos mos, tsis muaj ntxhiab thiab tsis qab, muaj zog zais lub zog thiab xim lub zog, melting point 1560 ~ 1580 ℃. Insoluble nyob rau hauv dej, dilute inorganic acid, organic solvent, roj, me ntsis soluble nyob rau hauv alkali, soluble nyob rau hauv concentrated sulfuric acid. Nws hloov daj thaum rhuab thiab dawb tom qab txias. Rutile (R-type) muaj qhov ntom ntawm 4.26g / cm3 thiab qhov ntsuas tsis pom kev ntawm 2.72. R hom titanium dioxide muaj huab cua tsis zoo, dej tsis kam thiab tsis yooj yim rau cov yam ntxwv daj, tab sis me ntsis tsis zoo. Anatase (Type A) muaj qhov ntom ntawm 3.84g / cm3 thiab qhov ntsuas tsis pom kev ntawm 2.55. Hom titanium dioxide lub teeb ua haujlwm tsis zoo, tsis tiv taus huab cua, tab sis qhov whiteness zoo dua. Nyob rau hauv xyoo tas los no, nws tau pom tias nano-loj ultrafine titanium dioxide (feem ntau yog 10 mus rau 50 nm) muaj cov khoom Semiconductor, thiab muaj kev ruaj ntseg siab, siab transparency, siab ua haujlwm thiab siab dispersibility, tsis muaj toxicity thiab xim nyhuv. |
Siv | Siv rau hauv cov xim, number case, yas, roj hmab, ntawv, tshuaj fiber ntau thiab lwm yam lag luam; Siv rau vuam electrode, refining titanium thiab manufacturing titanium dioxide Titanium dioxide (Nano) yog dav siv nyob rau hauv functional ceramics, catalysts, tshuaj pleev ib ce thiab photosensitive cov ntaub ntawv, xws li dawb. inorganic pigments. Cov xim dawb yog qhov muaj zog tshaj plaws, nrog lub zog zais zoo thiab xim nrawm, haum rau cov khoom siv dawb opaque. Hom rutile yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv cov khoom yas sab nraum zoov, uas tuaj yeem muab lub teeb pom kev zoo. Anatase feem ntau yog siv rau cov khoom siv sab hauv tsev, tab sis lub teeb xiav me ntsis, siab dawb, lub zog zais loj, muaj zog xim thiab zoo dispersion. Titanium dioxide yog dav siv los ua xim, ntawv, roj hmab, yas, enamel, iav, tshuaj pleev ib ce, number case, dej xim thiab roj xim pigment, kuj siv tau nyob rau hauv metallurgy, xov tooj cua, ceramics, electrode. |
