리튬-암모니아(Li(NH3)n) 용액을 이용한 열전기적 특성 실험
Experimental Study of Thermo-electric material using Lithium-Ammonia(Li(NH3)n) Solution
박한우, 김지범, 전준현
본 논문의 목적은 리튬-암모니아 솔루션(Li(NH3)n)의 실험을 통하여 암모니아물질의 임계점인 -40 ℃ 근처에서의 열전특성을 분석하고 이를 증명하는 것이다. 실험 결과 0.58 MPM~1.87 MPM을 갖는 리튬-암모니아 솔루션(Li(NH3)n)은 온도차(ΔT=0~15 ℃)에서 전류가 전압에 비례하는 열전전력을 발생시킨다는 사실을 확인하였다. 본 논문은 열전 물질 개발에 새로운 방향을 제시할 것이다.
The aim of this paper is, through the experiment of Lithium-Ammonia solutions (Li(NH3)n), to analyze and verify a thermoelectric-conversion property at near Ammonia-boiling point (-40℃ ). The experiment results show that the solutions with 0.58 MPM~1.87MPM generate thermoelectric power at temperature difference (ΔT=0~15 ℃) where Current is constantly proportional to Voltage. This paper provides a new insight into the development of a thermoelectric material.
