The sintering, microstructure, and phase composition of zirconia ceramics containing a sodium niobate addition have been studied. It has been shown that the addition leads to a decrease in the sintering temperature to 1400°С. The resulting materials are characterized by a high content of the tetragonal phase, a fine-crystalline structure, and a high flexural strength up to 440 MPa. The developed low-temperature materials can be used in dentistry as ceramic crowns.
