Abstract
A material composite that is vacuum-tight and resistant to thermal shocks is disclosed along with a method for the production thereof and to its use. A permanent connection between an aluminum oxide sapphire and an aluminum oxide ceramic is attained by a first connecting later comprised of a manganese-silicate glass, in which at least one of the metals molybdenum, tungsten, palladium or platinum is incorporated, and by a second connecting layer comprised of a manganese-silicate glass. To this end, the individual materials are fused by sintering. The material composite is used, for example, for inserting a window comprised of aluminum oxide sapphire into a housing for a light-ignitable thyristor.
