Title (EN) THERMOELECTRIC SKUTTERUDITE COMPOSITIONS AND METHODS FOR PRODUCING THE SAME
(FR) COMPOSITIONS DE SKUTTERUDITE THERMOÉLECTRIQUES ET LEUR PROCÉDÉ DE PRODUCTION
Abstract: front page image
(EN)Compositions related to skutterudite-based thermoelectric materials are disclosed. Such compositions can result in materials that have enhanced ZT values relative to one or more bulk materials from which the compositions are derived. Thermoelectric materials such as n-type and p-type skutterudites with high thermoelectric figures-of- merit can include materials with filler atoms and/or materials formed by compacting particles (e.g., nanoparticles) into a material with a plurality of grains each having a portion having a skutterudite-based structure. Methods of forming thermoelectric skutterudites, which can include the use of hot press processes to consolidate particles, are also disclosed. The particles to be consolidated can be derived from (e.g., grinded from), skutterudite-based bulk materials, elemental materials, other non- Skutterudite- based materials, or combinations of such materials.
(FR)Cette invention a trait à des compositions liées à des matériaux thermoélectriques à base de skutterudite. Ces compositions peuvent donner des matériaux dont les valeurs ZT sont meilleures que celles d’un ou plusieurs matériaux en vrac dont les compositions sont dérivées. Des matériaux thermoélectriques tels que des skutterudites de type N et de type P ayant des facteurs de mérite thermoélectriques élevés peuvent inclure des matériaux comprenant des atomes de remplissage et/ou des matériaux obtenus par agglomération de particules (comme des nanoparticules) dans un matériau qui présente une pluralité de grains, chaque grain comportant une partie qui possède une structure à base de skutterudite. L’invention concerne également des procédés de formation de skutterudites thermoélectriques, lesdits procédés pouvant inclure des processus de pressage à chaud pour consolider les particules. Les particules à consolider peuvent être dérivées (par broyage, par exemple) de matériaux en vrac à base de skutterudite, de matériaux élémentaires, de matériaux ne comprenant pas de skutterudite, ou de combinaisons de ces matériaux.
