Abstract: A pressure container having a container body, wherein at an upper end of the container body an end portion is formed integrally with the container body, which has a container opening and wherein the container body has a container bottom arranged at a lower end and formed integrally with the container body. A valve is arranged in and/or at the end portion. A suction pipe is arranged in a container interior and is connected in a fixed and fluid-tight manner to the valve. A pipe interior of the suction pipe is fluidically connected to a passage opening of the valve, and the suction pipe extends in the direction of the container bottom into a region of the container bottom and has a pipe opening in the region of the container bottom.

Abstract: Multilayer Ni/Nb/Ni interlayers form thin transient liquid films at reduced temperatures that enable the rapid joining of alumina ceramics, and produce joints of reliably high strength. Bulk alumina with polished and as-ground bonding surfaces have been successfully joined. The overall interlayer composition can exceed 95% Nb, and thereby provide an excellent thermal expansion match to alumina, alumina-matrix composites, and other materials. Fabrication of joints suitable for high-temperature applications is possible.
