Abstract

The aim of this paper is, through the experiment of Lithium-Ammonia solutions $(Li(NH_3)_n)$, to analyze and verify a thermoelectric-conversion property at near Ammonia-boiling point ($-40^{\circ}C$). The experiment results show that the solutions with 0.58 MPM~1.87 MPM generate thermoelectric power at temperature difference $({\Delta}T=0{\sim}15^{\circ}C)$ where Current is constantly proportional to Voltage. This paper provides a new insight into the development of a thermoelectric material.

본 논문의 목적은 리튬-암모니아 솔루션$(Li(NH_3)_n)$의 실험을 통하여 암모니아물질의 임계점인 $-40^{\circ}C$ 근처에서의 열전특성을 분석하고 이를 증명하는 것이다. 실험 결과 0.58 MPM~1.87 MPM을 갖는 리튬-암모니아 솔루션 $(Li(NH_3)_n)$ 은 온도차$({\Delta}T=0{\sim}15^{\circ}C)$에서 전류가 전압에 비례하는 열전전력을 발생시킨다는 사실을 확인하였다. 본 논문은 열전 물질 개발에 새로운 방향을 제시할 것이다.
