Method for obtaining thermoelectric materials with ZT value (figure of merit) higher than 1

摘要

method for thermoelectric materials with a zt larger than 1 is that partially or completely crystallized two - or multi-component oxide materials containing elements of group pu00f3u0142metali or metal ions in a quantity of at least 5 mole%, after ddaje reduction, advantageously in a hydrogen atmosphere, at a temperature above 200u00b0c, not less than 5 hours.as pu00f3u0142metali ions or metal ions are used and / or germanium antimony tellurium and / or and / or bismuth and / or lead and / or silver and / or cobalt. in order to obtain systems as reducing process is repeated several times in the temperature range of 300 - reduction of 450u00b0c in cycles favourably after 15 minutes.
