Abstract
A CaTiO-based oxide thermoelectric material and a preparation method thereof are disclosed. The CaTiO-based oxide thermoelectric material has a chemical formula of CaLaTiO, where 0<x≤0.4. The present disclosure makes it possible to prepare a CaTiO-based thermoelectric material with properties comparable to n-type ZnO, CaTiO, SrTiOand other oxide thermoelectric materials. Among them, the La15 sample has a power factor reaching up to 8.2 μWcmK(at about 1000 K), and a power factor reaching up to 9.2 μWcmKat room temperature (about 300 K); and a conductivity reaching up to 2015 Scm(at 300 K). The CaTiO-based oxide thermoelectric material exhibits the best thermoelectric performance among calcium titanate ceramics. The method for preparing the CaTiO-based oxide thermoelectric material of the present disclosure is simple in process, convenient in operation, low in cost, and makes it possible to prepare a CaTiO-based ceramic sheet with high thermoelectric performance.
