홈페이지논문 초록 (Abstract)
International transport property-measurement round-robins have been conducted by the thermoelectric annex under the International Energ y Agency (IEA) Implementing Agreement on Advanced Materials for Transportation (AMT). Two previous round-robins used commerci ally available bismuth telluride as the test material, with the ob jectives of understanding measurement issues and developing standard t esting procedures. This round-robin extended the measurement tempera ture range to 773 K.It was designed to meet the increasing demands for reliable transport data for thermoelectric materials used for power-g eneration applications. Eleven laboratories from six IEA-AMT member co untries participated in the study. A half-Heusler (n-type) material prepared by GMZ Energy was selected for the round-robin. The measured t ransport properties had a narrower distribution of uncertainty than previous round-robin results. The study intentionally included mult iple testing methods and instrument types. Over the full temperature ra nge, the measurement discrepancies for the figure of merit, ZT, in this round-robin were +/- 11.5 to +/- 16.4% from the averages.
