摘要

采用超高压法制备了NixCo4-xSb12 (x = 0.02~0.1)。研究了复合材料的组成、热电性能和显微组织。结果表明，超高压烧结制备的NixCo4-xSb12 (x = 0.02~0.1)具有良好的热电性能。低温热处理导致导电率和塞贝克系数降低。高温热处理使样品的电导率和塞贝克系数均有所提高

Thermoelectric Properties of NixCo4-xSb12 Fabricated by Ultra High Pressure Method

Ni_xCo_4-xSb₁₂ (x = 0.02~0.1) was fabricated by ultra high-pressure method. Composition, thermoelectric properties and the microstructure were investigated. The results indicate that Ni_xCo_4-xSb₁₂ (x = 0.02~0.1) fabricated by ultra high pressure sintering has good thermoelectric properties. Low temperature heat treatment leads to a decrease of the electric conductivity and Seebeck coefficient. High temperature heat treatment leads to an increase of both the electric conductivity and Seebeck coefficient of the samples
