Titanium Dioxide |13463-67-7
Khoom Description
Titanium dioxide tshwm sim nyob rau hauv cov xwm txheej zoo li cov ntxhia pob zeb rutile, anatase thiab brookite, thiab ntxiv rau ob hom kev kub siab, ib daim ntawv zoo li monoclinicbaddeleyite thiab ib daim ntawv zoo li orthorhombicα-PbO2, ob qho tib si pom tsis ntev los no ntawm Ries crater hauv Bavaria.Daim ntawv feem ntau yog rutile, uas kuj yog theem sib npaug ntawm txhua qhov kub.Cov metastable anatase thiab brookite theem ob hloov mus rau rutile thaum cua sov.Titanium dioxide yog siv cov xim dawb, tshuaj pleev thaiv hnub thiab UV absorber.Titanium dioxide hauv kev daws lossis kev ncua tuaj yeem siv los txiav cov protein uas muaj cov amino acid proline ntawm qhov chaw uas muaj proline. .
