Potassium titanate powder, friction adjusting material, resin composition, friction material, and friction member

摘要

To provide a potassium titanate powder that can avoid safety and health concerns and concurrently, during use in a friction material, can give excellent frictional properties.SOLUTION: A potassium titanate powder is formed of bar-like potassium titanate particles having an average length of 30 μm or more, an average breadth of 10 m or more, and an average aspect ratio of 1.5 or more, wherein the bar-like potassium titanate particles are represented by a composition formula K2TinO2n+1 (where n=5.5 to 6.5).SELECTED DRAWING: None
