  • Patent number: 11390568
    Abstract: To provide a ceramic composite and a production method therefor allowing ease of processing to be improved and fracture toughness to be improved simultaneously. The invention includes the steps of: preparing at least a liquid-form resin and a ceramic sintered body which has been sintered at a temperature which is 700° C. to 100° C. less than a sintering temperature at which a theoretical density is obtained; immersing the ceramic sintered body in the liquid-form resin, causing the liquid-form resin to infiltrate the ceramic sintered body; and hardening the infiltrated liquid-form resin to obtain a ceramic composite having a relative density of between 40% and 90% by causing the resin to infiltrate. Gaps where no resin has infiltrated are formed in the ceramic composite.
