Manufacturing of Reticulated Open-Cellular Aluminum Nitride Ceramic Foams

A process for the fabrication of open-cellular aluminum nitride foams by the replica technique avoiding the usage of organic solvents has been developed.

In order to meet the challenges of an increasing share of renewable energy sources and their efficient utilization, new concepts for (thermal) energy storage and climatization applications are mandatory. Currently, solutions based on small molecule (e. g. water) adsorption/desorption processes into porous compounds, for example zeolites (microporous alumosilicate adsorbents; pore size in nm range), are a focus of research. These ad-/desorption cycles involve heat transformation processes, which can be harnessed in thermal energy storage or climatization applications. [...]
