Sodium metatitanate is a chemical compound with the chemical formula Na2TiO3. This compound decomposes with treatment with hot water.[3] The name sodium metatitanate is also used incorrectly to refer to the compound sodium trititanate (Na2Ti3O7).
Production
[edit]Sodium metatitanate can be produced by heating titanium dioxide and sodium carbonate at 1000 °C:[4]
- TiO2 + Na2CO3 → Na2TiO3 + CO2
