ABSTRACT:
A method for producing composite materials by introducing additional phases into a porous body wherein a liquid precursor is infiltrated into the porous body, the liquid is decomposed to produce a desired phase, the body is fired for further densification, and the decomposed liquid is allowed to remain as an additional phase or reacts with the porous body to form an additional phase is disclosed. This allows for a novel method of introducing the additional phase, and by controlling the parameters such as infiltration time, firing schedule, porous body density, etc., the size, amount, extent and distribution of the added phases may be controlled.
