Abstract
Official abstract text for this publication.
A first bonding material composition according to the present invention is a bonding material composition used when aluminum nitride sintered bodies containing a rare-earth metal oxide are bonded to each other, in which the bonding material composition contains, in addition to an O element-containing aluminum nitride raw material, (a) as a fluorine compound, at least one of a fluorine compound of an alkaline-earth metal and a fluorine compound of a rare-earth metal, or (b) as a fluorine compound, at least one of a fluorine compound of an alkaline-earth metal and a fluorine compound of a rare-earth metal, and a rare-earth metal oxide.
First claim
Opening claim text (preview).
What is claimed is: 1 . An aluminum nitride bonded body in which aluminum nitride sintered bodies are bonded to each other with a bonding layer, wherein the bonding layer contains, as a crystal phase, AlN and at least one of a fluorine compound of an alkaline-earth metal and a fluorine compound of a rare-earth metal. 2 . The aluminum nitride bonded body according to claim 1 , wherein the fluorine compound of the alkaline-earth metal is an alkaline-earth metal oxyfluoride and the fluorine compound of the rare-earth metal is a rare-earth metal oxyfluoride. 3 . The aluminum nitride bonded body according to claim 1 , wherein the bonding layer contains, as a crystal phase, at least one of an alkaline-earth metal-aluminum oxide and a rare-earth metal-aluminum oxide. 4 . An aluminum nitride bonded body in which aluminum nitride sintered bodies are bonded to each other with a bonding layer, wherein the aluminum nitride sintered bodies have reaction layers at interfaces with the bonding layer, the reaction layers being formed by a reaction of an oxide contained in a aluminum nitride sintered bodies and a fluorine compound contained in a bonding material composition before the formation of the bonding layer, and the bonding layer contains, as a crystal phase, AlN and at least one of a fluorine compound of an alkaline-earth metal and a fluorine compound of a rare-earth metal. 5 . The aluminum nitride bonded body according to claim 4 , wherein the reaction layer contains at least one of an alkaline-earth metal oxyfluoride and a rare-earth metal oxyfluoride. 6 . The aluminum nitride bonded body according to claim 1 , having a bonding strength of 200 MPa or more. 7 . The aluminum nitride bonded body according to claim 4 , having a bonding strength of 200 MPa or more.
