摘要

研究了li掺杂NiO和li掺杂Ca/sub 0.05/Ni/sub 0.95/O(以Ca取代Ni改变晶格结构)在高温区的热电性能。采用软化学法制备氧化物粉末，并将其烧结成压缩板。化学处理大大缩短了整体制备时间。所得氧化物样品的塞贝克系数、电导率和导热系数与传统固相法制备的样品相似。该方法是制备氧化陶瓷的有效方法。

Preparation and thermoelectric properties of Li-doped Ca/sub 0.05/Ni/sub 0.95/O

Thermoelectric properties of Li-doped NiO and Li-doped Ca/sub 0.05/Ni/sub 0.95/O, with Ni substituted by Ca in order to alter the lattice structure, were investigated in high temperature region. The oxide powder was prepared by a soft chemical approach, and then was sintered in form of compressed pallets. The chemical processing greatly shortens the overall preparation time period. Seebeck coefficient, electrical conductivity and thermal conductivity of the oxide samples were similar to those of the samples prepared via traditional solid-state approach. The novel chemical processing is effective to prepare the oxide ceramics.
