'''Titanium dioksida''', juga dikenal sebagai '''titanium(IV) oksida''' atau '''titania''', adalah oksida titanium yang terjadi secara lami, dengan rumus kimia TiO2. Bila digunakan sebagai pigmen, disebut titanium putih, Pigment White 6 (PW6), atau CI 77891. Umumnya oksida ini bersumber dari ilmenite, rutile dan anatase. Titanium dioksida memiliki aplikasi yang luas, dari cat sampai tabir surya hingga pewarna makanan. Bila digunakan sebagai pewarna makanan, ia memiliki E number, yaitu E171. |
