Scalable and shapable nacre-like ceramic-metal composites based on deformable microspheres.

ABSTRACT: Natural nacre that consists of brittle minerals and weak organics exhibits a high fracture toughness while retaining a high strength. The exceptional mechanical performance of nacre is attributed to its hierarchical structure like a 'brick-and-mortar' structure, which has inspired the development of tough ceramic-based composites. However, the practical applications of biomimetic structural ceramics are hindered by limited material size, fabrication efficiency and flexibility of being molded into various shapes. We herein report the fabrication of nacre-like ceramic-metal composites based on deformable alumina microspheres coated with nickel salt. Green bodies are produced by assembling the composite microspheres in molds with different shapes. During the hot-pressing sintering of the gree
