Abstract: The compositions of the present invention comprise alumina and minor proportions of a ternary glass sintering aid from the system: BaO-MgO-SiO2. The compositions can be sintered in a reducing atmosphere to provide ceramics which find particular utility in electrical devices, e.g., in multilayer ceramic sandwiches. The compositions are particularly amenable to formation by doctor blade slip casting techniques.
