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