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...
