(a) XRD pattern in energy-dispersive mode of i-QC starting material at ambient conditions. Filled circles indicate peaks representative of a secondary phase (AlFe3) resulting from the synthesis procedure. (b) Temperature dependence of XRD patterns for i-QC. Notes: (*) MgO from surrounding sleeve; (·) AlFe3; (°) graphite peak from the surrounding capsule.
