Optimized processes for obtaining the braze-welded joints of oxide ceramics based on Al2O3 and ZrO2 by pressure welding of ceramics with ceramics and ceramics with metals are developed. It is established that these braze-welded joints are prepared in the 1300–1600°C temperature range with pressure holding for 30–120 min under 15–25 MPa. The samples of welded pilot products that can be operated in both neutral and protective environment (up to 1500–1800°C) are produced according to the processes developed.
