| 简介 |
本发明系关於一种接合材组成物、氮化铝接合体及其制法；也就是说，本发明之接合材组成物、氮化铝接合体及其制法系在比较低之温度，无产生麻烦之气体，良好且安定地进行氮化铝接合体间之接合。本发明之第1接合材组成物系使用在接合包含稀土类金属氧化物之氮化铝接合体间之际之接合材组成物，除了包含氧(O)元素之氮化铝原料以外，还包含(a)硷土类金属氟化合物和稀土类金属氟化合物之至少一种，来作为氟化合物，或者是包含(b)硷土类金属氟化合物和稀土类金属氟化合物之至少一种，来作为氟化合物，并且，还包含稀土类金属氧化物。 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. |
