METHOD FOR FORMING INORGANIC FIBER-REINFORCED CERAMICS

PURPOSE:To minimize residual stress strain in forming and obtain a compact having excellent fracture toughness by a press forming, such as cold isostatic press (CIP) forming, by using a mixture of inorganic fibers with ceramic powder having an average diameter at a specific ratio to the average diam...

Zusammenfassung:PURPOSE:To minimize residual stress strain in forming and obtain a compact having excellent fracture toughness by a press forming, such as cold isostatic press (CIP) forming, by using a mixture of inorganic fibers with ceramic powder having an average diameter at a specific ratio to the average diameter of the inorganic fibers. CONSTITUTION:(A) Inorganic fibers, e.g., SiC, Si3N4, Al2O3, or whiskers of graphite or potassium titanate, having
