A mechanism of zinc blende to rocksalt structural transformation of silicon carbide was studied. The new transformation pathway was based on an orthorhombic intermediate state with two Silicon carbide units per cell. Kinetic aspects of the transition were characterized by analyzing the activation enthalpy and variation of activation volume with respect to pressure.

Abstract
A mechanism of zinc blende to rocksalt structural transformation of silicon carbide was studied. The new transformation pathway was based on an orthorhombic intermediate state with two Silicon carbide units per cell. Kinetic aspects of the transition were characterized by analyzing the activation enthalpy and variation of activation volume with respect to pressure.
