Zusammenfassung:	Invention relates to the technology of production of corundum ceramics and can be used for obtaining the large-dimension complex-profile articles made of high-purity corundum ceramics by method of soldering from separate elements. Ceramic solder for soldering the ceramics with the ceramics contains in per cent by weight: SiO2 - 45.0-58.0; CaO - 15.0-25.0; Al2O3 - 10.0-13.0; addition of the metal from the group Mn, Fe, Co, Cr - 1.0-3.0; eutectic mixture BaO-B2O3-SiO2 in the ratio 1:0.41: 0.52 - 9.0-2.1. The problem of developing of durable and thermally reliable joint is solved.
