Mechanochemical Nucleation and Stability of Newly-Formed Phases

  • Published:
Refractories and Industrial Ceramics Aims and scope

Abstract

Nucleation of new phases originated by mechanochemical activation of the reactants is considered. The decrease in nucleation energy of high-melting powders modified with silicon alkoxide is achieved via formation of carbon clathrates in SiO2 and self-organized high-activity ensemble with a specified proportion of cybotactic groups. The stability of newly-formed β-SiC and mullite synthesized by a mechanochemical method is discussed.
