PLATY POTASSIUM TITANATE, PROCESS FOR PRODUCING THE SAME, AND FRICTION MATERIAL

摘要

Platy potassium titanate having a mean major diameter of 1 - 100 µm and a mean aspect ratio of 3 - 500 and obtainable by subjecting magnesium or lithium potassium titanate to an acid treatment to thereby prepare platy titanate, immersing the platy titanate in a potassium hydroxide solution and then subjecting it to calcination.
