Abstract

See full text

A composite and pressureless sintering process for making whisker-reinforced alumina composites using a nitride modifier. The whiskers are milled to an aspect ratio of less than 10. Green preform bodies are surrounded by a carbonaceous material during the sintering process to prevent direct exposure of the body surface to the atmosphere within the sintering furnace during the sintering step.
