PURPOSE:To obtain ceramics for a thin film head which is decreased in pores and has excellent wear resistance and workability by adding a prescribed amt. of a specific compd. to Al2O3-TiC ceramics thereby improving the sinterability thereof. CONSTITUTION:One or >= two kinds among La2O3, CeO2 and Sm2O3 are added at 1-10wt% to 100wt% essential component consisting of 15-60wt% TiC and the balance Al2O3. Since the wettability between Al2O3 and TiC is thereby improved, the sinterability is improved, the remaining pores are decreased and the wear resistance is improved. One or >= two kinds among Cr2O3, TiO2 and NiO are further added at 1-5wt% thereto, by which the ceramics material for the thin film magnetic head having the small grain size structure and good workability is obtd. |
