SODIUM HEXATITANATE AND METHOD FOR PRODUCTION THEREOF

摘要

Disclosed is a sodium hexatitanate which has a novel shape, shows excellent abrasion resistance when used in a friction material, and shows excellent reinforcing properties when used in a resin composition. Also disclosed is a method for producing the sodium hexatitanate. Further disclosed is a friction material comprising the sodium hexatitanate. Specifically disclosed is a sodium hexatitanate having an average particle diameter of 2 to 5 µm and an amorphous shape. The sodium hexatitanate is produced by burning a ground mixture prepared by the mechanochemial grinding of a titanium source and a sodium source, or is produced from a sodium trititanate which is produced by burning a ground mixture prepared by the mechanochemial grinding of a titanium source and a sodium source.
