Sodium metatitanate is a chemical compound with the chemical formula Na2TiO3. This compound decomposes with treatment with hot water.[2] The name sodium metatitanate also incorrectly refers to the compound sodium trititanate (Na2Ti3O7).

Production

Sodium metatitanate can be produced by heating titanium dioxide and sodium carbonate at 1000 °C:[3]

TiO2 + Na2CO3 → Na2TiO3 + CO2
