摘要

the invention relates to the use of u0441u0443u043fu0435u0440u0438u043eu043du043du043eu0433u043e alloy Li0.15Cu1.85S as new u0442u0435u0440u043cu043eu044du043bu0435u043au0442u0440u0438u0447u0435u0441u043au043eu0433u043e material. the alloy has Li0.15Cu1.85S found high coefficient of electronic heat u044d.u0434.u0441.(coefficient of thermoelectric) with a value of 200 to 600 u043cu043au0432 / to in the range of 300 - 500u00b0u0441. alloy Li0.15Cu1.85S has sufficiently high electronic conductivity in hundreds of om 1u2219u0441u043c - 1 over the temperature interval of 100 500u00b0u0441,in the state of material has low thermal conductivity u0441u0443u043fu0435u0440u0438u043eu043du043du043eu043c about 1 u0432u0442u2219u043c - 1u2219u043a - 1. the listed properties provides the high values of u0431u0435u0437u0440u0430u0437u043cu0435u0440u043du043eu0439 ZTu22651 thermoelectric efficiency.the study of electronic conductivity and coefficient of thermal u044d.u0434.u0441.in the temperature range of 20 to 600u00b0u0441 and ion conductivity, leading to the degradation of u0442u0435u0440u043cu043eu044du043bu0435u043au0442u0440u0438u0447u0435u0441u043au043eu0433u043e modulerevealed: the temperature range of the material is u0442u0435u0440u043cu043eu044du043bu0435u043au0442u0440u0438u0447u0435u0441u043au043eu0433u043e 300 500u00b0u0441.
