Bioceramics for artificial dental crowns in dentistry have been fabricated by sol-gel process and melting method, respectively. Sintering characteristics have been investigated after compositing powder mixtures relative to leucite content(0∼30wt.%) added to glass matrix. Highly pure leucite powders have been fabricated by sol-gel process and glass powders have been manufactured with 20∼30㎛ particle size by a melting method. Sintering temperatures could be controlled from 1020℃ to 1175℃ relative to the powder mixtures of leucite and glass powders. The relative sintered density was 80∼83% of theoretical density. Shrinkage was about 20∼25% after sintering.
