The wettability of Y–Al–Si–O–N oxynitride glasses and its application in silicon nitride joining

摘要: Abstract In the present work, first, wettability of Y–Al–Si–O–N oxynitride glasses on Si3N4 substrates was investigated. It found that glass depended ratios Y2O3/Al2O3, i.e. when ratio Y2O3/Al2O3 increased, corresponding substrate improved. Based ceramics can be successfully joined using with best wettability. proved a proper joining temperature is important for sound joints; lower would result in incomplete contact brazing layer while higher than 1600° cause separation joints by complete drainage into bulk ceramics. range experiment time, to prolong time benefit shear strength.
