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 m 2 /g, 40 to 100 mass% of titanium oxide having a specific surface area of 7 to 200 m 2 /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. |
