    摘要： Provided is an alkali-metal titanate in which the content and adhesivity of the fibrous potassium titanate is significantly reduced.The alkali-metal titanate includes 0.5 mol to 2.2 mol of potassium oxide in terms of potassium atoms, 0.05 mol to 1.4 mol of sodium oxide in terms of sodium atoms, and 0 mol to 1.4 mol of lithium oxide in terms of lithium atoms relative to 1 mol of alkali-metal hexatitanate, in which a 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 relative to 1 mol of alkali-metal hexatitanate is 1.8 mol to 2.3 mol; and the alkali-metal titanate has a single phase conversion ratio of 85% to 100%, a fiber ratio of 0% by volume to 10% by volume, and a moisture content of 0% by mass to 1.0% by mass.

    摘要： A method for producing a potassium titanate easily produces a potassium titanate having a high single phase ratio and a significantly reduced fibrous potassium titanate content in high yield. The method for producing a potassium titanate includes: a mixing step that mixes a titanium raw material with a potassium raw material, the titanium raw material including 0 to 60 mass % of titanium oxide having a specific surface area of 1 to 2 m2/g, 40 to 100 mass % of titanium oxide having a specific surface area of 7 to 200 m2/g, and 0 to 4.5 mass % in total of one or more materials selected from titanium metal and titanium hydride, and the potassium raw material including a potassium compound; a calcination step that calcines a raw material mixture obtained by the mixing step at a calcination temperature of 950 to 990° C.; and a grinding step that grinds a calcined powder obtained by the calcination step using one or more means selected from a vibrating mill and an impact pulverizer.
