Composite Ceramics and Ceramic Particles and Method for Producing Ceramic Particles and Bulk Ceramic Particles
Abstract:
Methods for producing Polymer Derived Ceramic (PDCs) particles and bulk ceramic components and compositions from partially cured gelatinous polymer ceramic precursors and unique bulk composite PDC ceramics and unique PDC ceramic particles in size and composition. Methods of making fully dense PDCs over approximately 2 μm to approximately 300 mm in diameter for applications such as but not limited to proppants, hybrid ball bearings, catalysts, and the like. Methods can include emulsion processes or spray processes to produce PDCs. The ceramic particles and compositions can be shaped and chemically and materially augmented with enhancement particles in the liquid resin or gelatinous polymeric state before being pyrolyzed into ceramic components. The resulting ceramic components have a very smooth surface and are fully dense, not porous as ceramic components from the sol-gel process.
