Description
  • Magnesium silicon nitride MgSiN2 was prepared by direct nitridation of Si/Mg2Si/Mg/Si3N4 powder compact in a temperature range 1350-1420oC. The thermal stability examination showed that MgSiN2 is stable up to 1400oC at 0.1 MPa N2 pressure. The activation energy of decomposition of MgSiN2 calculated from the temperature dependence of mass loss in the range of 1400-1650oC is deltaH = 501 kJ/mol. The time dependence and nitrogen pressure dependence of MgSiN2 decomposition was also investigated at constant temperature. MgSiN2 is stable at 1560oC in 0.6 MPa nitrogen atmosphere. Using these experimental data together with the heat capacity published in a literature the Gibbs energy of formation of MgSiN2 was calculated in a temperature range 25-2200oC.
