Ceramic-polymer composites and methods. The ceramic-polymer composites, in powder and/or pellet forms, comprise a plurality of core-shell particles, where: each of the core-shell particles comprises a core and a shell around the core; the core comprises a ceramic selected from the group of ceramics consisting of: Al.sub.2O.sub.3, Fe.sub.2O.sub.3, ZnO, ZrO.sub.2, and SiO.sub.2; and the shell comprises a polymer selected from the group of polymers consisting of: PC copolymers, polyetherimide (PEI), polyetherimide (PEI) copolymers, polyphenyl sulfone (PPSU), polyarylethersulfone (PAES), and poly ether sulfones (PES). In powder form, the core-shell particles are in a substantially dry powder form having a moisture content of less than 2% by weight. In pellet form, shells of adjacent core-shell particles are joined to resist separation of the adjacent core-shell particles and deformation of a respective pellet. Methods of forming a ceramic-polymer composite comprise: superheating a mixture of polymer, solvent, and ceramic, to dissolve the polymer in the solvent; agitating the superheated mixture while substantially maintaining the mixture at an elevated temperature and pressure; and cooling the mixture to cause the polymer to precipitate on the particles of the ceramic and thereby form a plurality of the present polymer-ceramic core-shell particles. Methods of molding a part comprise subjecting a powder of the present polymer-ceramic core-shell particles that substantially fills a mold to a first pressure while the powder is at or above a first temperature above a melting temperature (T.sub.m) of the polymer.
