  • Porous titanate compound particles and method for producing same
    Patent number: 10479695
    Abstract: Provided are porous titanate compound particles capable of giving excellent fade resistance and moisture-proof properties when used in a friction material, a friction material composition, a friction material, a friction member, and a method for producing the porous titanate compound particles. Porous titanate compound particles have a cumulative pore volume of 5% or more within a pore diameter range of 0.01 to 1.0 ?m, are each formed of titanate compound crystal grains bonded together, and each includes a treated layer formed on a surface thereof and made of a hydrophobic surface treatment agent.
    Type: Grant
