A SiGe alloy-based electrical insulation node of thermoelectric battery was built using  graphite and AlN ceramic. Both of them have high thermal conductivity and are thermomechanically compatible with SiGe alloys within a wide temperature range. Vacuum soldering with Ti-Cu alloy anddiffusion welding were used in making the electrical insulation node. A metallographic and mechanical study of the produced contacts was carried out. The operation mode of the created electrical insulation node has been established.
