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.
