Niaj hnub no' s zej zog, kev lag luam titanium dioxide yog ib lub hnab sib xyaw, thiab muaj ntau cov neeg cuav thiab cov neeg tsis zoo. Pom tias titanium dioxide muaj ntau yam kev siv, thiab kev lag luam loj thiab nruab nrab kev txiav txim los ntawm tuj, qee cov neeg muag khoom tsis txaus ntseeg coj cov kev pheej hmoo thiab coj mus ua qhov zoo. Cov qauv rau cov qhua tuaj noj mov yog cov tseem, tab sis thaum lawv ua tiag, lawv yuav yog cuav. Cov khoom raug xa tawm raws li cov khoom lag luam tiag tiag rau cov neeg yuav khoom. Thaum cov neeg yuav khoom pom cov khoom cuav, lawv hais tias cov khoom yog tib yam li cov qauv rau ntau yam thiab nws tsis tuaj yeem xa rov qab cov khoom. Vim tias tus nqi pheej yig ntawm rutile titanium dioxide thiab qhov ntau ntawm nws, muaj ntau cov khoom cuav ntawm cov lag luam, feem ntau suav nrog cov hauv qab no:
(1) Ntim cov khoom lag luam titanium dioxide rau hauv titanium dioxide tuaj.
(2) Anatase type titanium dioxide yog siv los ua piv txwv hom rutile lossis ib feem ntawm anatase hom titanium dioxide yog sib xyaw ua hom rutile.
(3) Sau cov ntaub ntawv xws li calcium carbonate, lithopone, barium sulfate, thiab lwm yam yog sib xyaw ua ke rau hauv rutile titanium dioxide lossis anatase titanium dioxide.
Hauv qhov no, Tus Thawj Coj Yao ntawm Lub Chaw Haujlwm Muag Khoom ntawm Tuam Tshoj Shuangli Pab Pawg tau hais tias qhov tseeb ntawm titanium dioxide tuaj yeem txiav txim raws li cov hauv qab no:
