Abstract
A method of making a ceramic composite comprises forming a wet ceramic composition comprising a plurality of discrete ceramic components and a fluxing agent dissolved in a solvent. At least a portion of the solvent is removed from the wet ceramic composition to form a dried ceramic composition comprising the plurality of discrete ceramic components coated with the fluxing agent. The dried ceramic composition is sintered to form the ceramic composite, the sintering being carried out at a sinter temperature sufficient to fuse the discrete ceramic components at bridging sites formed where two or more of the discrete ceramic components coated with fluxing agent are in physical contact.
