Tsim kom muaj barium metatitanate nrog molten barium carbonate (ntxiv barium chloride los yog sodium carbonate li cov pab tiv thaiv):
TiO2+BaCO3 = BaTiO3+CO2 ↑
Insoluble hauv dej los yog dilute sulfuric acid, tab sis soluble hauv kub concentrated sulfuric acid los yog molten potassium hydrogen sulfate:
TiO2+H2SO4 = TiOSO4+H2O
Txawm hais tias kev daws tau los ntawm kev zom titanium dioxide hauv kub concentrated sulfuric acid yog acidic, nws kuj tuaj yeem raug kua dej thaum rhaub thiab rhaub kom tau hydrated titanium dioxide (type-hom titanic acid) uas yog insoluble hauv acids thiab alkalis. Yog tias alkali tau ntxiv rau qhov kev npaj tshiab titanium hydrochloric acid tov, tshiab hydrated titanium dioxide (type-hom titanic acid) tau txais, uas yog rov cuam tshuam ntau dua β-hom titanic acid thiab tuaj yeem yaj nyob rau hauv dilute acid thiab mloog alkali. Tom qab tau yaj nyob rau hauv kev sib xyaw sodium sodium hydroxide tov, hydrated titanate nrog cov tshuaj lom neeg cov tshuaj Na2TiO3 · H2O tuaj yeem ua kom zoo los ntawm cov tshuaj.
Titanium dioxide thiab carbon hmoov tau nias rau hauv ib qho loj thiab coked, rhuab txog 1070-1170K, los tsim cov gaseous titanium tetrachloride.
TiO2+2Cl2+2C = TiCl4 + +2CO ↑
Qhov kev tawm tsam no tseem ceeb heev rau kev rho tawm ntawm titanium. Magnesium lossis sodium tuaj yeem txo cov titanium tetrachloride yooj yim.
Cov tshuaj tiv thaiv ntawm titanium dioxide nrog COCl2 (phosgene), SOCl2 (thionyl chloride), CHCl3 (trichloromethane), CCl4 (carbon tetrachloride) thiab lwm cov tshuaj rov ua dua los kuj tseem siv tau los npaj cov titanium tetrachloride:
TiO2+CCl4 = TiCl4 + CO2CO2 ↑ (Cov tshuaj tiv thaiv yog ua tiav ntawm 770K)
