Abstract
The present invention is a fibrous monolithic ceramic product of high deny and a process for making the product. The product has a microstructure of coated fibers with planes of weakness between a core of each coated fiber and its respective coat or between each coated fiber and adjacent coated fibers, thereby toughening the product. The planes of weakness are sufficiently weak to deflect a crack from normal to the plane of weakness to a direction parallel to the plane of weakness. The green body from which the product is formed, can be plastically deformed at room temperature, formed in near-net-shape, and densified by pressureless sintering.
