Summary

A UHV apparatus for solid-state bonding of ceramic and metal single crystal and polycrystalline materials is described. The apparatus is especially designed for the production of clean interfaces in bicrystal joints between crystallographically preoriented flat crystal platelets. Sandwich-like pieces of 35 mm maximum height and a welded surface area of 10 mm × 15 mm can be manufactured in the apparatus which is subdivided into a cleaning chamber, a parking station, and a welding unit. The maximum welding temperature is 1800°C. Information is given on the preparation of single crystals for diffusion bonding. First experiments in the UHV bonding of polycrystalline Nb to polycrystalline alumina are described.
