Title: Hans De Haas: Iron Powder Production Innovation.
Introduction.
Hans De Haas is an inventor associated with Meerbusch, Germany, and Mannesmann Aktiengesellschaft. His recorded patent concerns a method for producing iron powder with distinctive fiber-like particles and low bulk density.
Latest Patents.
De Haas is credited with 1 patent, titled “Method of Making Iron Powder.” The process produces iron oxide particles by spray calcination and reduces the oxide substantially in carbon monoxide at temperatures between 800°C and 1,000°C. Heat-treating the oxide before calcination or adding calcium oxide can promote the formation of iron fibers. The reducing atmosphere may include hydrogen, or hydrogen may be used in the final reduction phase. After reduction, the iron cake is cooled and broken up in a grinder. The resulting powder has low bulk density because its particles are fibrous and non-porous; further grinding can increase its bulk density.
Career Highlights.
De Haas’s patent describes a production method that combines controlled reduction, optional hydrogen treatment, and grinding to shape the properties of iron powder. The disclosed approach focuses on producing fibrous iron particles and adjusting the powder’s bulk density.
Collaborations.
De Haas is associated with Mannesmann Aktiengesellschaft. His listed coworkers include Klaus Grebe and Josef Hewing.
Conclusion.
Hans De Haas’s recorded invention addresses iron powder production through a process designed to create fibrous, non-porous particles and allow adjustment of bulk density.
