The article presents experimental results on thermoelectric properties of In0.2Ce0.1Co4Sb12.3 alloy, prepared by rapid quenching technique. The initial material, typically in the form of thin ribbons, has quasi-amorphous structure. Usually, the ribbons are crashed to powder with subsequent compaction by hot-pressing or spark plasma sintering techniques. However, the thermoelectric properties of as-prepared ribbons have been unknown. In this work the thermopower and the electrical resistivity of In0.2Ce0.1Co4Sb12.3 ribbons are studied for the first time at temperatures from 100 K to 750 K. Temperature stability range of the quasi-amorphous structure, and the crystallization kinetics were investigated.
