Industrialized Half-Heusler materials and thermoelectric modules therefrom


Since 2009 the Isabellenhütte has been actively involved in Heusler alloy research again. Since then we have been working on thermoelectric Half-Heusler compounds. Our purpose is the development of a melt metallurgical manufacturing process for these materials, which is able to be industrialized. We have also a focus on the development of thermoelectric modules using our Half-Heusler materials. In 2017 the Isabellenhütte built up an industrial pilot line production, which starts with the raw elements and ends up with thermoelectric modules. The ambition is to demonstrate an industrial scale material manufacturing and an automated assembling process of Half-Heusler modules in a constant high quality.

Now the project is in the process development phase. It has already succeeded to produce first 10 kilogram batches of P-type and N-type materials. In the framework of the H2020 funded project INTEGRAL it is planned to enlarge the production scale up to 50 Kg batches in 2019. Furthermore it is already possible to manufacture small single legs from these ingots with industrial processes. Concerning the modules first tests of an automated assembly by a self-developed production line are running. This work is a part of the German national funded project thermoHEUSLER².

Today the Isabellenhütte Heusler GmbH & Co. KG is able to show first results of P-type and N-type material from 10 kilogram ingots and results from thermoelectric modules made by these materials.

Curriculum Vitae

Daniel Zuckermann is currently development engineer in the department R&D Alloys and Applications at Isabellenhütte Heusler GmbH & Co KG.
He is responsible for the development of thermoelectric materials and components. He is the project manager of Isabellenhütte for the German national funded project thermoHEUSLER² and the European Union Horizon 2020 project INTEGRAL. Daniel Zuckermann completed an apprenticeship as physics laboratory assistant at the Isabellenhütte Heusler in 2008. Subsequently he received his Dipl. Ing. in Material and Manufacturing Technology at Technical University of Mittelhessen in 2011. In 2011 and 2012 he worked as process engineer in the foundry of Isabellenhütte. In this time he had
his focus on the metallurgical manufacturing process of functional materials. Since 2013 he is working in the department R&D Alloys and Applications, focused in the development of new electro technical functional materials and devices therefrom.
