Inorganic Materials Aims and scope

Abstract

The kinetics of the h-BN → c-BN transformation in a mixture of composition 78% h-BN + 5% NH4F + 2% B + 15% Mg are studied at 5 GPa and temperatures from 1670 to 1910 K. The activation energy of c-BN formation, temperature-dependent reaction rate constant, strength of the forming c-BN particles, and density of paramagnetic defects in c-BN are evaluated.
