The study of sintering, microstructure and phase composition of zirconia ceramics containing the additive - sodium niobate. It is shown that the use of an additive helps to reduce the sintering temperature to 1,400 ° C. The obtained materials are characterized by a high content of the tetragonal phase, a fine-crystalline structure and high strength up to 440 MPa during bending. The developed low-temperature materials can be used in dentistry as ceramic crowns.
