Abstract
A method of forming a ceramic monolith comprises exposing a pre-formed metal substrate to a NaCl filtered continuous wave laser beam of about 50 to 100 W power and about 80 to 315 W/cm.sup.2 power density in an atmosphere of a gas desired to react with the metal, allowing for the gas to diffuse into the metal substrate at a temperature effective to permit reaction thereof to form the ceramic monolith, and cooling the monolith.
