METHOD FOR PRODUCTION OF ALKALI TITANATE, METHOD FOR PRODUCTION OF HOLLOW POWDER OF ALKALI TITANATE, ALKALI TITANATE AND HOLLOW POWDER THEREOF PRODUCED BY THE METHODS, AND FRICTION MATERIAL COMPRISING THE ALKALI TITANATE OR THE HOLLOW POWDER THEREOF

摘要

Disclosed is a method for producing potassium titanate which is suitable as a friction material for a friction slide member. Also disclosed is a friction material. Specifically disclosed is a method for producing potassium titanate, which comprises the steps of: mixing an aggregate or granule of a titanium compound with an aggregate or granule of a potassium compound homogeneously in a vibration rod mill to produce a mixture; and burning the mixture to cause the reaction between the titanium compound with the potassium compound to produce potassium titanate. The method can produce potassium titanate in a simple manner and at low cost.
