    Abstract: The present invention is a method for fabricating shaped monolithic ceramics and ceramic composites, and the ceramics and composites made thereby. The method of the present invention includes three basic steps: (1) Synthesis or other acquisition of a porous preform with an appropriate composition, pore fraction, and overall shape is prepared or obtained. The pore fraction of the preform is tailored so that the reaction-induced increase in solid volume can compensate partially or completely for such porosity. It will be understood that the porous preform need only be sufficiently dimensionally stable to resist the capillary action of the infiltrated liquid reactant; (2) Infiltration: The porous preform is infiltrated with a liquid reactant; and (3) Reaction: The liquid reactant is allowed to react partially or completely with the solid preform to produce a dense, shaped body containing desired ceramic phase(s). The reaction in step (3) above is a displacement reaction of the following general type between a liquid species, M(l), and a solid preform comprising the compound, NBXC(s): AM(l)+NBXC(s)=AMXC/A(s)+BN(l/g) where MXC/A(s) is a solid reaction product (X is a metalloid element, such as, for example, oxygen, nitrogen, sulfur, etc.) and N(l/g) is a fluid (liquid or gas) reaction product. A, B and C are molar coefficients.

    Abstract: Diamond heat spreaders are produced having thermal properties approaching that of pure diamond. Diamond particles of relatively large grain size are tightly packed to maximize diamond-to-diamond contact. Subsequently, smaller diamond particles may be introduced into the interstitial voids to further increase the diamond content per volume. An interstitial material is then introduced which substantially fills the remaining voids and should have favorable thermal properties as well as form chemical bonds with the diamond. Alternatively, the packed diamond may be subjected to ultrahigh pressures over 4 GPa in the presence of a sintering aid. The resulting diamond heat spreader has diamond particles which are substantially sintered together to form a continuous diamond network and small amounts of a sintering agent. The final heat spreader exhibits superior heat transfer properties advantageous in removing heat from various sources such as electronic devices and minimized difference in thermal expansion from the heat source.

    Abstract: The present invention is directed to new processes in which electromagnetic levitation forces are used to infiltrate a porous matrix with a solid infiltrant. In such processes, controlled heating of these components, melting the infiltrant while both components are subjected to levitation forces, and containerless transportation and subsequent contact of both components results in the infiltration of the porous matrix. Such containerless processing provides for infiltrated porous matrices which are free of contaminants generally introduced by the containers used in traditional methods of infiltration.
