Abstract
An object is to provide a sintered body causing less chipping and having a sufficiently higher polishing rate than a conventional AlTiC sintered body, and providing a sufficiently smooth air bearing surface. The sintered body according to the present invention consists of Al2O3, a compound represented by the chemical formula (1) below, and a composite oxide containing Al and Ti, TiCxOy (1) wherein x+y≦1, x>0 and y>0.
Claims4
A sintered body consisting of:
- Al2O3;
- a compound represented by the chemical formula (1) below;
- and
- a composite oxide containing Al and Ti,
- TiCxOy (1)
- wherein x+y≦1, x>0 and y>0.
A method for producing a sintered body, comprising a step of hot pressing a raw material powder containing Al2O3, TiC and TiO2, under a pressure in the range of 100 to 200 kgf/cm2.
