| Izakhiwo Zomzimba Nezamakhemikhali | Impushana emhlophe.
impushana emhlophe enokwakheka okuthambile, engenaphunga futhi ayinambitheki, amandla okufihla aqinile namandla ombala, indawo encibilikayo 1560~1580 ℃. Ayincibiliki emanzini, i-dilute inorganic acid, i-organic solvent, uwoyela, inyibilika kancane ku-alkali, inyibilika ku-cocentrated sulfuric acid. Ibaphuzi uma ishisa futhi ibemhlophe ngemva kokupholisa. I-Rutile (uhlobo lwe-R) inobuningi obungu-4.26g/cm3 kanye nenkomba ye-refractive engu-2.72. Uhlobo luka-R lwe-titanium dioxide lunokumelana okuhle kwesimo sezulu, ukumelana namanzi futhi akulula ukuba nezici eziphuzi, kodwa ubumhlophe obumpofu kancane. I-Anatase (Uhlobo A) inokuminyana okungu-3.84g/cm3 kanye nenkomba ye-refractive engu-2.55. Thayipha i-titanium dioxide ukumelana nokukhanya akulungile, akumelani nesimo sezulu, kodwa ubumhlophe bungcono. Eminyakeni yamuva, kutholakale ukuthi i-nano-size ultrafine titanium dioxide (imvamisa i-10 kuya ku-50 nm) inezindawo ze-Semiconductor, futhi inokuqina okuphezulu, ukukhanya okuphezulu, umsebenzi ophezulu kanye nokuhlakazeka okuphezulu, akukho ubuthi nomphumela wombala. |
| Sebenzisa | Isetshenziswa kupende, uyinki, ipulasitiki, irabha, iphepha, imicu yamakhemikhali nezinye izimboni;Isetshenziselwa ukushisela i-electrode, ukucwenga i-titanium nokukhiqiza i-titanium dioxideI-Titanium dioxide (Nano) isetshenziswa kakhulu kubumba obusebenzayo, ama-catalysts, izimonyo nezinto ezithinta ukukhanya, njengokumhlophe. izingulube ze-inorganic. I-pigment emhlophe iyona enamandla kakhulu, enamandla amakhulu okufihla kanye nokushesha kombala, ifanele imikhiqizo emhlophe opaque. Uhlobo lwe-rutile lufaneleka ngokukhethekile ukusetshenziswa emikhiqizweni yepulasitiki yangaphandle, enganikeza ukuzinza okuhle kokukhanya. I-Anatase isetshenziselwa kakhulu imikhiqizo yasendlini, kodwa ukukhanya okuluhlaza kancane okuluhlaza, ubumhlophe obuphezulu, amandla amakhulu okucasha, umbala oqinile nokuhlakazeka okuhle. I-Titanium dioxide isetshenziswa kabanzi njengopende, iphepha, irabha, ipulasitiki, koqweqwe lwawo, ingilazi, izimonyo, uyinki, umbala wamanzi nombala wombala kawoyela, ingasetshenziswa futhi kwezensimbi, umsakazo, izitsha zobumba, i-electrode. |
