Title: Cecilia Elgelid: Innovator in Soft Magnetic Materials

Introduction

Cecilia Elgelid is a notable inventor based in Helsingborg, Sweden. She has made significant contributions to the field of soft magnetic materials, holding 2 patents that showcase her innovative approach to material science.

Latest Patents

One of her latest patents is titled "Iron powder and method for the preparation thereof." This invention involves a process for creating an insulated soft magnetic powder. The process includes mixing particles of a soft magnetic iron base powder with an acidic, aqueous insulating-layer forming solution, in which MgO has been dissolved. The mixture is then dried to form an electrically insulating Mg-containing layer on the particle surfaces. The patent also covers the powder itself and compressed soft magnetic powder cores prepared from it.

Another significant patent is "Compressed soft magnetic materials." This invention outlines a process for preparing a compressed soft magnetic powder core. The process involves compacting an iron-based powder, whose particles are insulated by a chromium-containing layer, at a pressure between 300 and 1500 MPa. The compacted body is subsequently heated to a temperature sufficient for achieving stress relief and recrystallization of the iron base material.
