Connection method of parts from refractory oxides

FIELD: metallurgy. SUBSTANCE: connection method of parts from refractory oxides involves polishing of attached surfaces, their alignment and heating. A layer of material forming solid solution at least with one of materials of the attached parts is applied at least to one of the polished attached surfaces. Melting temperature of solid solution is lower than melting temperature of each of the materials of the attached parts. After that, aligned parts are annealed at the temperature above solid solution formation temperature. EFFECT: invention allows connecting parts from refractory oxides, reducing losses for dissipation of optic emission, heat and sound owing to diffusion of an optic boundary. 10 cl
