Abstract
PURPOSE:To obtain a fiber reinforced silicon nitride ceramic having excellent mechanical characteristics and especially high toughness value, by blending silicon nitride powder with sintering auxiliary powder and fibers in a solvent to give slurry, freeze drying the slurry in vacuum and sintering. CONSTITUTION:Silicon nitride powder is blended with sintering auxiliary powder and fibers in a solvent to give slurry, which is dried by vacuum freeze drying and sintered. By applying vacuum freeze drying method, blended powder can be sintered while maintaining dispersion state of the fibers in the silicon nitride matrix uniform. The silicon nitride powder preferably contains a large amount of alpha type crystal. Yttria, titania, alumina, magnesia or compound oxides thereof may be cited as the sintering auxiliary. For example, short-fibers and filaments of silicon carbide may be cited as the fibers. Water and various kinds of organic solvents may be cited as the solvent.
