Abstract:
(EN) A ceramic joined body having a first aluminum-oxide-based sintered compact, a second aluminum-oxide-based sintered compact, an aluminum-oxide-based joint layer positioned between the first aluminum-oxide-based sintered compact and the second aluminum-oxide-based sintered compact, and an aluminum-oxide-based protruding part connected to the aluminum-oxide-based joint layer, the mean diameter of closed pores of the aluminum-oxide-based protruding part being 0.8 to 1.5 times the mean diameter of closed pores of each of the first aluminum-oxide-based sintered compact and the second aluminum-oxide-based sintered compact.
(FR) Cette invention concerne un corps jointé en céramique constitué d'un premier compact fritté à base d'oxyde d'aluminium, d'un second compact fritté à base d'oxyde d'aluminium, d'une couche de jointure à base d'oxyde d'aluminium agencée entre le premier compact fritté à base d'oxyde d'aluminium et le second compact fritté à base d'oxyde d'aluminium, et d'une partie protubérante à base d'oxyde d'aluminium jointe à la couche de jointure à base d'oxyde d'aluminium, où le diamètre moyen des alvéoles fermées de la partie protubérante à base d'oxyde d'aluminium est de 0,8 à 1,5 fois le diamètre moyen des alvéoles fermées de chacun du premier compact fritté à base d'oxyde d'aluminium et du second compact fritté à base d'oxyde d'aluminium.
(JA) 第1の酸化アルミニウム質焼結体と、第2の酸化アルミニウム質焼結体と、第1の酸化アルミニウム質焼結体と第2の酸化アルミニウム質焼結体との間に位置する酸化アルミニウム質接合層と、酸化アルミニウム質接合層に繋がる酸化アルミニウム質凸部と、を有するセラミック接合体であって、酸化アルミニウム質凸部の閉気孔の平均径が、第1の酸化アルミニウム質焼結体および第2の酸化アルミニウム質焼結体のそれぞれの閉気孔の平均径の0.8倍以上1.5倍以下である。
