FIELD: chemistry.
SUBSTANCE: invention relates to technical ceramics, namely to production of electroconductive ceramic composites filled with tin and/or its alloys, which can be used as heating elements in direct electric heating systems. Electroconductive composition includes a ceramic matrix based on alumina ceramics in amount of 70-85 wt.% and an electroconductive filler in the form of tin or a tin-lead alloy in amount of 15-30 wt.% and can be used as heating elements in direct electric heating systems in aggressive media with operating temperatures of up to 200 °C.
EFFECT: obtained material has specific electrical resistance of 0,115-0,159 mcOhm⋅m.
