Abstract
Ceramic nanocomposite and methods for manufacturing thereof. One method comprising: receiving a fired green ceramic body comprising ceramic matrix; introducing to the fired green ceramic body submicron particles; and introducing at least one type of location-controlling dopant at an amount that is sufficient to cover the majority of the ceramic matrix grain boundaries, as well as the majority of the interfaces between the submicron particles and the ceramic matrix grains but less than an amount that would result in a concentration that exceeds the bulk solubility limit of the location-controlling dopant ions in the ceramic matrix, at the ceramic nanocomposite sintering temperature.
