High-Temperature Compounds of Oxide Ceramics Produced Through the Plastic Plates of Niobium and Noble Metals

Abstract

Optimal processes for obtaining the compounds 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 compounds are prepared in the 1300–1600°C temperature range with 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 developed processes.
