With a total of two patents to his name, Gerest's work has implications for the manufacturing of permanent magnets.
Latest Patents
Gerest's latest patents focus on a process for preparing ferrite powders of Barium (Ba), Strontium (Sr), and/or Lead (Pb). These ferrite powders are intended to be incorporated into elastomeric, thermoplastic, or thermosettable binders for the production of flexible or rigid permanent magnets. The process involves creating a mixture of iron oxides and carbonates of Ba, Sr, and/or Pb. Additionally, one or more alkaline earth halides are added in a total proportion of 0.5 to 15% of the total weight of the mixture. Furthermore, one or more oxygenated boron compounds, particularly alkaline and/or alkaline earth borates, are included in a proportion of 0.2 to 7%. The mixture is then calcined between 850°C and 1100°C for at least 15 minutes.
