Abstract

The joining of the aluminium with $Al_2O_3$ permits receiving materials with better utilitarian properties in the wide range of temperatures. These joints find applications in the new fields of technology and industry. In the case of processing of the metal-$Al_2O_3$ joints the important problems are obtaining the stable joining and the right wettability between the metal and the ceramic, as well as controlling the phenomena which can occur at the interface. The subject of the paper is the analysis of the chosen physical and chemical factors which influence the formation of the stable metal/ceramic joints. Moreover, the phenomena which can occur at the metal-ceramic interface are discussed.
