Titanium(IV) oxide CAS 13463-67-7 Selelekela
boleng
Phofo e tšoeu ea amorphous. Ho na le mefuta e meraro ea titanium dioxide e teng ka tlhaho: rutile ke kristale ea tetragonal; Anatase ke kristale ea tetragonal; Plate perovskite ke kristale ea orthorhombic. Bosehla ha bo chesa hanyenyane 'me bo sootho mochesong o matla. Ha e qhibilihe ka metsing, hydrochloric acid kapa nitric acid kapa e hlapolla sulfuric acid le metsoako ea lintho tse hlapollang, e qhibilihang ka concentrated sulfuric acid, hydrofluoric acid, e qhibilihang hanyenyane ka alkali le hot nitric acid. E ka belisoa ka nako e telele ho qhibiliha ka concentrated sulfuric acid le hydrofluoric acid. E kopana le sodium hydroxide e qhibilihisitsoeng ho etsa titanate. Ha lithempereichara tse phahameng, e ka fokotsoa hore e be titanium e tlaase-valent ka hydrogen, carbon, metal sodium, joalo-joalo, 'me e sebetsane le carbon disulfide ho etsa titanium disulfide. Refractive index ea titanium dioxide ke eona e kholo ka ho fetisisa ka mebala e tšoeu, 'me mofuta oa rutile ke 8. 70, 2.55 bakeng sa mofuta oa anatase. Kaha ka bobeli anatase le poleiti titanium dioxide e fetoha rutile ha mocheso o le holimo, lintlha tse qhibidihang le tse belang tsa poleiti ea titanium le anatase li batla li le sieo. Ke feela rutile titanium dioxide e nang le ntlha e qhibilihisang le ntlha e belang, ntlha e qhibilihisang ea rutile titanium dioxide ke 1850 °C, sebaka se qhibilihisang moeeng ke (1830 lefats'e 15) °C, le ntlha ea ho qhibiliha ho matlafatsa oksijene ke 1879 °C. , 'me ntlha ea ho qhibiliha e amana le ho hloeka ha titanium dioxide. Sebaka se belang sa rutile titanium dioxide ke (3200 mobu 300) K, 'me titanium dioxide e fetoha hanyenyane mochesong ona o phahameng.
Mokhoa
Industrial titanium oxide sulfate e qhibiliha ka metsing ebe e tlhotliloeng. Ammonia e ile ea eketsoa ho thefula pula e kang gauntlet, ebe ea tlhotloa. Ebe e qhibiliha ka tharollo ea oxalic acid, ebe e kenngoa fatše ebe e tlhotliloeng ka ammonia. Mocheso o fumanoeng o omisitsoe ho 170 ° C ebe o besoa ho 540 ° C ho fumana titanium dioxide e hloekileng.
Bongata ba tsona ke merafo ea mekoti e bulehileng. Titanium primary ore beneficiation e ka aroloa ka mekhahlelo e meraro: pele ho karohano (e sebelisoang hangata karohano ea makenete le mokhoa oa ho arola matla a khoheli), karohano ea tšepe (mokhoa oa ho arohana ha makenete), le karohano ea titanium (karohano ea matla a khoheli, karohano ea makenete, karohano ea motlakase le mokhoa oa ho phaphamala). Melemo ea li-placers tsa titanium zirconium (haholo-holo libaka tse lebōpong la leoatle, tse lateloang ke libaka tse ka hare ho naha) li ka aroloa ka mekhahlelo e 'meli: karohano e boima le khetho. Ka 1995, Setsi sa Patlisiso se Felletseng sa Ts'ebeliso ea Ts'ebeliso ea Zhengzhou sa Lekala la Geology le Mehloli ea Liminerale se ile sa amohela mokhoa oa karohano ea matla a khoheli, karohano ea matla a khoheli le leaching ea asiti ho ruisa molemo morafong o moholo oa rutile o Xixia, Profinseng ea Henan, e seng e fetile tlhahiso ea liteko. litsupa tsohle li boemong bo ka sehloohong Chaena.
tshebediso
E sebelisoa e le sesebelisoa sa tlhahlobo ea spectral, ho lokisa letsoai la titanium le hloekileng haholo, li-pigments, litlolo tsa polyethylene le li-abrasives. E boetse e sebelisoa indastering ea meriana, capacitive dielectric, li-alloys tse hanyetsanang le mocheso o phahameng, le tlhahiso ea seponche sa titanium e hanyetsanang le mocheso o phahameng.
E sebelisoa ho etsa titanium dioxide, titanium sponge, titanium alloy, rutile ea maiketsetso, titanium tetrachloride, titanium sulfate, potassium fluorotitanate, aluminium titanium chloride, joalo-joalo Titanium dioxide e ka sebelisoa ho etsa pente e tšoeu ea boemo bo holimo, rabara e tšoeu, likhoele tsa maiketsetso. , li-coatings, li-electrode tsa welding le li-rayon tse fokotsang khanya, li-plastiki le li-fillers tsa pampiri tsa maemo a holimo, hape li sebelisoa lisebelisoa tsa mehala ea puisano, metallurgy, khatiso, khatiso le dae, enamel le mafapha a mang. Rutile e boetse e le thepa e ka sehloohong ea liminerale bakeng sa ho hloekisa titanium. Titanium le li-alloys tsa eona li na le thepa e ntle haholo joalo ka matla a phahameng, letsoalo le tlase, ho hanyetsa kutu, ho hanyetsa mocheso o phahameng, ho hanyetsa mocheso o tlase, ho se chefo, joalo-joalo, 'me li na le mesebetsi e khethehileng e kang ho monya khase le superconductivity, kahoo li sebelisoa haholo lifofane, indasteri ea lik'hemik'hale, indasteri e bobebe, ho tsamaea ka sekepe, bongaka, ts'ireletso ea naha le nts'etsopele ea lisebelisoa tsa leoatle le likarolo tse ling. Ho feta 90% ea liminerale tsa "titanium" tsa lefats'e li sebelisetsoa ho hlahisa mebala e tšoeu ea titanium dioxide, 'me sehlahisoa sena se sebelisoa haholo ho penta, rabara, polasetiki, pampiri le liindasteri tse ling.
