| 摘 要： | 用高温熔融法合成了Ag和In共掺的单相n型(AgIn)xPb1-2xTe化合物,研究了(AgIn)掺杂量x对(Ag-In)xPb1-2xTe(x=0.01～0.05)物相组成及热电性能的影响.结果表明:掺杂量x≤0.04时得到单相四元化合物,x=0.05时样品中出现了组成为AgInTe2第二相;(AgIn)xPb1-2xTe化合物的Seebeck系数随着x增加而增大,电导率随着掺杂量x增加而降低;化合物的热导率随着掺杂量x增大而减小;当x=0.01时,(AgIn)xPb1-2xTe化合物的热电性能指数值最大,在800K时达到1.1.

| Abstract: | Single-phase n-type (AgIn)xPb1-2xTe compounds were synthesized using the melting reaction method.Influences of (AgIn) substituting for Pb on the constituent phases and thermoelectric properties of the (AgIn)xPb1-2xTe(x=0.01~0.05) were investigated.Results indicate that single phase compound is obtained when the (AgIn) substitution fraction x≤0.04.However,the second phase (AgInTe2) was observed in the sample withx=0.05.The Seebeck coefficient increases gradually with the increasing of the (AgIn) substitution fraction x,and the electrical conductivity of the compounds decreases with the increasing of x.Thermal conductivity decreases with the increasing of x.In all of the n-type (AgIn)xPb1-2xTe compounds,(AgIn)0.01Pb0.98Te compound has the greatest ZT value,reaching 1.1 at 800K. |
