Abstract
Magnetic head slider material consisting of 5.about.10 percent by weight of silicon, 1.3.about.7.8 percent by weight of tungsten silicide and essentially balanced silicon carbide. And it is method for producing said magnetic head slider material that at the time of which the mixed powder consisting of silicon carbide, carbon and tungsten is sintered, cellulose is also mixed with said mixed powder and sintered together at the same time. And then fibrous micropores are caused to the sintered body by the above-described sintering, after that molten metallic silicon infiltrated into fibrous micropores.
