LEPIDOCROSITE TYPE POTASSIUM MAGNESIUM TITANATE AND METHOD FOR PRODUCTION THEREOF, AND FRICTION MATERIAL.

摘要

A lepidocrosite type potassium magnesium titanate having a composition represented by the fomula: K0.2-0.7Mg0.4Ti1.6O3.7-4; and a method for producing the lepidocrosite type potassium magnesium titanate which comprises treating a lepidocrosite type potassium magnesium titanate having a composition represented by the fomula: K0.8Mg0.4Ti1.6O4 with an acid, and then firing the resultant solids. The lepidocrosite type potassium magnesium titanate can be advantageouly used for a friction material as a friction controlling agent.
