Abstract: Methods, processes, and systems for producing bulk ceramics from agglomerations of partially cured gelatinous polymer ceramic precursor resin droplets, without using sponge materials to form gas pathways in the polymer bodies. Ceramics can be formed in hours. Resin droplets can be produced with a sprayer where liquid polymer precursors, mixed with a curing agent, are sprayed forming droplets which are partially cured, collected, and compressed into shapes. Ceramic porosity can be varied, droplet particle sizes can be controlled by adjusting liquid and gas pressure, orifice size, during spraying. Partially cured droplets can be formed via an emulsion process and size controlled by emulsion liquid and surfactant selection parameters.
