“…Due to its elevated sintering temperature, Al 2 O 3 is metallized with refractory metals. Molybdenum and tungsten are often used because of their low coefficient of thermal expansion [12,79]. Different metallizing pastes containing Mo and Mn powders can be dissolved in a solvent and used (Table V).…”

“…Typical mechanical strengths of the joints vary from 10 to 50 MPa. Stress concentration areas (especially in the ceramic counterpart) and design limitation are among the major restrictions of those methods [5,10,12].…”

“…[5,10,12,15,33,34]. Some examples are shown in Table II [8,12] Brazing has been defined by the American Welding Society (AWS) as a joining process that takes place above 450 °C using filler metals or alloys which flows by capillary forces and whose melting temperature is lower than the solidus temperature of the base materials. Filler metals or alloys should adhere to the surface of the base materials [35][36][37][38].…”

Metal-ceramic joining has slowly but steadily become an important manufacturing step. The evolution of joining processes has allowed ceramics to be used in combination with metals in a number of hybrid devices from traditional light bulbs and seals to improved cutting tools and modern monitoring and measuring electronic devices. New joining methods and newer approaches to conventional methods have been developed aiming at joints characterized by improved reliability, and interfaces capable of withstanding high-temperature resistance with minimum residual stresses. A summary of recent improvements on alternative approaches to ceramic-metal joining as well as new developments on brazing are presented herein. The present review also focuses on recent advances towards brazing metallized ceramics and the selection of filler alloys, since in a scenario that includes joining by laser and direct bonding with liquid transient phases, brazing continues to be by far the most widely used approach to joining as a result of its low-cost and possibility to join intricate geometries for large-scale production. Finally, methods to evaluate the mechanical strength and residual thermal stresses are presented in addition to alternative approaches to minimize residual stresses and, consequently, improve joint reliability.

“…Reliable strength, high operational temperatures, excellent thermal and electrical conductivity often characterize brazed ceramic/metal couples. In addition, brazing is a relatively simple process and easily automated [14,15]. Brazing can be carried out in a single step (direct brazing) using active filler alloys containing Ta, Nb, V and, especially, Ti.…”

“…Recent studies have contributed to reveal the mech- anisms involved in the reaction of the Ti present in the filler alloy with the surface of engineering ceramics, especially alumina, zirconia and silicon nitride [4,10,14]. Alternatively, the ceramic component can be previously metallized and then brazed using conventional active-metal free filler alloys [4,[15][16][17][18].…”
