Titanium dioxide bụ titanium oxide sitere n'okike nke nwetara nlebara anya zuru ebe niile n'ihi ngwa dị iche iche a na-etinye na ụlọ ọrụ dị iche iche.Site na mkpuchi anwụ ruo agba, agba nri na fotocatalyst, titanium dioxide bụ ihe dị iche iche nke nwere ikike ya na nhazi ya pụrụ iche.Na blọọgụ a, anyị ga-elebakwu anya na yaỌdịdị nke titanium dioxidema chọpụta otú o si eme ka ọtụtụ ojiji ya dị mfe.
N'ime obi nke titanium dioxide dị iche iche bụ nhazi kristal ya.Titanium dioxide dị n'ụdị kristal atọ: rutile, anatase, na brookite.N'ime ndị a, rutile na anatase bụ ụdị kachasị ewu ewu, nke ọ bụla nwere nhazi atọm pụrụ iche.
Rutile bụ ihe kasị kwụsie ike na ukwuu ụdịtitanium dioxidena e ji mara ya ok lattice Ọdịdị.Nhazi nke titanium na oxygen atoms na rutile na-eme ka ọ bụrụ ihe ntanetị dị elu, na-eme ka ọ bụrụ ihe nzacha UV dị mma na pigmenti, mkpuchi na ọbụna sunscreen.Ọdịdị dị nso nke Rutile na-enyekwa aka na nkwụsi ike ya dị elu, na-eme ka ọ dị mma maka ngwa ihe na-eguzogide corrosion.
Anatase, n'aka nke ọzọ, nwere usoro na-emeghe ma na-adịchaghị obere ma gosipụta ihe dị iche iche ma e jiri ya tụnyere rutile.Amara maka ọrụ fotocatalytic pụrụ iche, anatase achọpụtala ngwa na mpaghara dị ka nrụzi gburugburu ebe obibi, ebe na-ehicha onwe ya, na ọbụna mmepụta hydrogen site na nkewa mmiri.Nhazi atọm pụrụ iche dị na anatase na-enyere ọgbọ abụọ nke oghere eletrọn rụọ ọrụ nke ọma mgbe ekpughere ya na ìhè, na-enye ya ike fotocatalytic.
Ike titanium dioxide ịdị adị n'ụdị nanostructures dị iche iche na-eme ka ọ dịkwuo mma.Nanoscale titanium dioxide nwere mpaghara elu dị elu na oke olu ma na-egosipụta mmeghachi omume na-emewanyewanye na ihe ọkụkụ ọkụ, na-eme ka ọ baa uru na ngwa dị ka fotovoltaics, sensọ na mkpuchi antimicrobial.Ikike ịkwa akwa nanostructures titanium dioxide na-emepe ụzọ ọhụrụ maka itinye ya na teknụzụ dị elu.
Ịghọta nhazi nke titanium dioxide dị oke mkpa iji kwalite arụmọrụ ya maka ngwa ngwa.Site n'ịchịkwa kristal ụdị, urughuru nha na elu Njirimara, na-eme nchọpụta na injinia nwere ike mma-tue naNjirimara nke titanium dioxideiji gboo mkpa nke ụlọ ọrụ dị iche iche.Ma ọ na-eji ike ya na-egbochi UV na nhazi nke anwụ ma ọ bụ na-etinye aka na ọrụ photocatalytic ya maka mmezi gburugburu ebe obibi, nhazi nke titanium dioxide bụ ihe atụ maka ọdịdị ya.
Na nchịkọta, nhazi nke titanium dioxide, gụnyere ụdị kristal ya na nanostructure, na-akwado ọrụ ya dị ịrịba ama na ọrụ dị iche iche.Site n'iwepụta usoro mgbagwoju anya ya, ndị ọkà mmụta sayensị na ndị na-emepụta ihe na-aga n'ihu na-emepe ohere zuru oke nke titanium dioxide, na-emeghe ụzọ maka ngwa ọhụrụ na ngwọta na-adịgide adịgide.Ka anyị na-abanyekwu n'ime nhazi-ihe onwunwe nke titanium dioxide, anyị nwere ike ịtụ anya ịhụ ọganihu ọzọ n'iji ihe onwunwe ya pụrụ iche na-erite uru na ọha mmadụ na gburugburu ebe obibi.
