PURPOSE:To manufacture a substrate for head which provides friction resistance and sliding characteristic by selecting the optimum amount of Al2O3. CONSTITUTION:Aluminum oxide (Al2O3) of 1-40wt%, silicon oxide (SiO2) of 1-3wt% and Fe2O2, Cr2O3, MnO2 and a kind or two or more kinds of rare earth oxides of 0.2-2wt% are added to the main elements consisting of zirconium oxide (ZrO2) of 80-94mol% and yttrium oxide (Y2O3) of 6-20mol%. A substrate having high friction resistance and sliding characteristic can be manufactured by selecting optimum amount of Al2O3 within the range of 1-40wt%. |
