热电材料是一类可以将热能和电能直接相互转化的新型功能材料。塞贝克系数作为评价热电材料性能的重要参数,其准确测量尤为关键。基于准确测量方法,建立了塞贝克系数的溯源路径,研究了塞贝克系数测量仪器的溯源性,验证了测量方法的准确性,以P型碲化铋Bi2Te3块体热电材料作为测量对象进行了测量不确定度评定,其相对扩展不确定度为0.46%～2.52%(k=2)。
Abstract
The thermoelectric materials are new functional materials, which can make the mutual transformation of thermal and electric energy directly. The Seebeck coefficient is the key parameter to evaluate the property of thermoelectric materials and its accurate measurement is very important. Based on the accurate measurement method, the traceability path of Seebeck coefficient was established, and the traceability of test apparatus were studied. The measurement uncertainty of P-type bismuth telluride Bi2Te3 bulk thermoelectric material was evaluated, and the relative expanded uncertainty was 0.46%～2.52% (k=2).
