null Congratulations Dr Jayakumari!

Congratulations to Dr Sethulakshmy Jayakumari  who successfully defended her thesis September 10th. Sethulakshmy did an excellent presentation of the trial lecture: “Production of Mn by electrolyses – state of the art and future prospects” followed by the presentation of her PhD thesis “Formation and characterization of β-and α-Silicon Carbide produced during Silicon/Ferrosilicon process”.

Sethu giving lecture. PhotoJayakumari has done her PhD work in the SFI Metal Production research domain “Primary Metal Production”. Professor Merete Tangstad has been the candidate’s supervisor and senior research scientist Eli Ringdalen, SINTEF Industry, has been the candidate’s co-supervisor.

In her PhD she studied the transformation of carbon to β- SiC and then the transformation α-SiC. The main findings are that the SiC formation transform directly through the solid carbon, but that it also can be produced through a gas/gas reactions and produce a solid SiC on the surface of the carbon materials. She also verified the production of elemental silicon in SiC at temperatures substantially lower than reference temperature of 1800 C. 

The Assessment Committee has been:

  • Prof.Dr.-Ing. Alexandros Charitos, TU Bergakademie Freiberg, Germany
  • Assist. Prof. PhD Leili Tafaghodi, University of British Columbia, Canada
  • Professor Kjell Wiik, NTNU
