Title:
CERAMIC MATERIAL AND ABRASION RESISTANT MEMBER USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/061358
Kind Code:
A1
Abstract:
Provided is a ceramic material of an aluminum oxide group which has sufficient strength as well as sufficient other mechanical properties and in which there is very little shedding of particles by greatly reducing the particle size of aluminum oxide in a ceramic having aluminum oxide as the main phase. In this ceramic material, a second phase which comprises a compound carbonitride of Ti and Me which is represented by (Ti,Me)(C,N) (provided that Me is one type or two types or more of the group 3-11 transition elements) is dispersed at 0.05-19.5 volume% in a first phase having aluminum oxide as the main component.
