Alkali metal titanic acid in which the content ratio of fibrous potassium titanate is highly reduced and the adhesion is greatly reduced is provided. An alkali metal titanic acid, characterized in that, with respect to 1 mol of hexatitanic acid, it comprises: 0.5-2.2 mol of potassium oxide in terms of potassium atom, 0.05-1.4 mol of sodium oxide in terms of sodium atom, and Lithium oxide is 0 to 1.4 moles in terms of lithium atoms, and the total content of potassium oxide in terms of potassium atoms, sodium oxide in terms of sodium atoms, and lithium oxide in terms of lithium atoms is 1.8 to 2.3 per mole of hexatitanic acid. moles, the alkali metal titanic acid has a single-phase rate of 85 to 100%, a fiber rate of 0 to 10% by volume, and a moisture content of 0 to 1.0% by mass. |
