With a total of 2 patents to his name, Grebe's work focuses on innovative methods for creating iron powder with unique properties.
Latest Patents
Grebe's latest patents include a method for making iron powder that features fiber-like particles. This process involves reducing iron oxide powder in a CO/N₂ atmosphere at temperatures ranging from 750°C to 1200°C. A critical aspect of this method is the limitation of hydrogen content to 15% (vol) of the CO content before metallic iron precipitation occurs. Additionally, sulfur compounds are maintained in the reducing atmosphere to enhance the process. Another patent details a method of making iron powder through spray calcination, where iron oxide particles are reduced in CO at temperatures between 800°C and 1000°C. This method may also involve heat treatment or the addition of CaO to promote the formation of iron fibers.
