摘要： Provided is an alkali metal titanate which, when used as a constituent material of a friction material, is excellent in heat resistance and friction force and capable of effectively suppressing wear of a mating material disposed to face the friction material. The alkali metal titanate includes a sodium atom and a silicon atom. The content of the sodium atom is 2.0 to 8.5 mass %. The content of the silicon atom is 0.2 to 2.5 mass %. The ratio of the content of an alkali metal atom other than the sodium atom to the content of the sodium atom is 0 to 6.

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.
