Abstract

Ceramic-metallic composites are disclosed along with the processes for their manufacture. The present invention improves high temperature strength of Al2O3—Al composites by displacing aluminum in the finished product with other substances that enhance the high temperature strength. Each process commences with a preform initially composed of at least 5% by weight silicon dioxide, and the finished product includes Al2O3, aluminum and another substance.
