Background and activities

PhD project title: Condensation of SiO and CO in silicon production. Started in July 2017

FIELDS OF INTEREST

- Studying of SiO and CO condensation reactions kinetics.
- Characterization of industrial samples and condensation products from SiO and CO by TEM, SEM, XPS, XRD, EDX, Raman, FT-IR.
- Theories on mechanism of formation of condensates
- Calculation of temperature and partial pressure intervals for condensation products, for industrial applications
- HSC Chemistry modeling of species in the gas and solid phase
- Study of crystallographic defects in nanostructured compounds
- Impurities containing Fe, Al, Ca and Ti in MG-Si
