Ihlabathi elinomdla le-Titanium Dioxide: i-Anatase, i-Rutile kunye ne-Brookite

I-Titanium dioxide yiminerali yendalo esetyenziswa kwimizi-mveliso eyahlukeneyo, kuquka ukuveliswa kweepeyinti, iiplastiki kunye nezithambiso. Kukho iintlobo ezintathu eziphambili zetitanium dioxide:i-anatase, i-rutile kunye ne-brookite. Ifomu nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo, okuzenza zibe zizifundo ezinomdla zokufunda.

I-Anatase yenye yeendlela eziqhelekileyo zetitanium dioxide. Iyaziwa ngokusebenza kwayo okuphezulu kwaye ihlala isetyenziswa njenge-catalyst kwi-chemical reactions. I-Anatase ikwasetyenziswa njengebala lemibala kwiipeyinti nakwizigqumathelo nakwimveliso yeeseli zelanga. Isakhiwo sayo esiyingqayizivele sekristale sinommandla ophezulu, okwenza kube yinto efanelekileyo yokusetyenziswa kwe-catalytic.

IRutile lolunye uhlobo lwetitanium dioxide esetyenziswa kakhulu kushishino. Eyaziwa ngokuba yi-high refractive index, idla ngokusetyenziswa njengebala elimhlophe kwiipeyinti, iiplastiki kunye nephepha. I-Rutile ikwasetyenziswa njengesihluzo se-UV kwi-sunscreen kunye nezinye izithambiso ngenxa yeempawu zayo ezigqwesileyo zokuthintela i-UV. Isalathisi sayo esiphezulu se-refractive senza ukuba luncedo ekuveliseni iilensi ze-optical kunye neglasi.

I-Brookite yindlela encinci eqhelekileyo ye-titanium dioxide, kodwa iseyinto ebalulekileyo ngokwayo. Iyaziwa ngokuba yi-conductivity ephezulu yombane kwaye isetyenziselwa ukuveliswa kwezixhobo zombane ezifana neeseli zelanga kunye nezinzwa. I-Brookite iphinda isetyenziswe njenge-pigment emnyama kwiipende kunye neengubo, kunye neempawu zayo eziyingqayizivele zenza ukuba ibe yinto ebalulekileyo kwizicelo ezahlukeneyo.

Ngelixa i-anatase, i-rutile, kunye ne-brookite zonke ziintlobo ze-titanium dioxide, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa. Ukuqonda umahluko phakathi kwezi fomu kubalulekile ekusebenziseni ngokufanelekileyo kumashishini ahlukeneyo. Enoba isetyenziswa ekwenzeni i-catalytic applications, njengebala kwipeyinti, okanye kwizixhobo zombane, uhlobo ngalunye lwetitanium dioxide lunendima yalo.

Ukuqukumbela, ihlabathi le-titanium dioxide lahluke kakhulu, kunye ne-anatase, i-rutile kunye ne-brookite zonke zineempawu zazo ezizodwa kunye nokusetyenziswa. Ukususela ekusetyenzisweni njengezinto ezibangela ukuba kubekho ii-pigments kunye nendima yayo kwizixhobo zombane, ezi ntlobo zetitanium dioxide zidlala indima ebalulekileyo kuluhlu olubanzi lwemizi-mveliso. Njengoko ukuqonda kwethu kwezi zixhobo kuqhubeka nokuphucula, sinokulindela ukusetyenziswa okutsha kwe-anatase, i-rutile, kunye ne-brookite kwiminyaka ezayo.
