Experimental study on the phase formation of MgxB2 (x=0.8, 1.0, 1.2)
Phase formation of Magnesium diboride Mgx B2(x=0.8, 1.0, 1.2) by in situ reaction of Magnesium (Mg) and Boron (B) at different annealing temperature by varying the nominal Mg composition was compared. The X-ray difffraction pattern indicates that Magnesium Oxide (MgO) is the major secondary phase....

| Summary: | Phase formation of Magnesium diboride Mgx B2(x=0.8, 1.0, 1.2) by in situ reaction of Magnesium (Mg) and Boron (B) at
different annealing temperature by varying the nominal Mg composition was compared. The X-ray difffraction pattern
indicates that Magnesium Oxide (MgO) is the major secondary phase. Some unreacted Mg was found for nominally
stoichiometric and Mg excess samples annealed at or
below 750°C. However, no unreacted Mg was detected
by XRD for Mg deficient samples. Scanning Electron microscopy images show the porous nature of synthesised samples. |
