With a total of 2 patents, Hoffmann's work has the potential to enhance efficiency and effectiveness in the industry.

Latest Patents

Hoffmann's latest patents focus on a process for manufacturing solid cathodes used in reduction cells for aluminum production. The solid cathodes are designed with at least one workface that can be wet by the precipitated metal. The starting materials, which include titanium, boron, and carbon in powder form, are mixed in specific proportions. This mixture is then heated under a neutral or reducing atmosphere to temperatures ranging from 1600°C to 2200°C, held for 5 to 45 minutes. The resulting reaction product, which contains pores and channels, is further heated to 2250°C to 2600°C for 10 to 60 minutes to form a compact titanium diboride/carbon eutectic. Finally, the solid cathode is cooled to room temperature.
