Metallization of surfaces of ceramics Is preliminary made for creation of one-piece
connections. The soldered seam is created between the metallized surfaces. The
soldering is carried out by soft or firm solders by method of radiating heating. Solder steals up taking into account close equality of factors of thermal expansion with ceramics.
On figure one–piece connections of ceramics among themselves, and ceramics with metal are presented. Similar quality connections with others dielectrics are received also. Considering high durability of the ceramics. It is possible to recommend the given method of formation of one–piece connections for hardening of the tool of different function.

Durability of connection is commensurable with durability of ceramics at a stretching.
