Abstract: The accurate phase boundary of MgAlON/(AlN+MgAlON) in MgO-AlN-Al2O3 ternary system, has not been determined precisely so far. In the present study, the lattice parameters of MgAlON solid solution with various compositions were determined precisely with X-ray powder diffraction. According to the relationship between the lattice parameters of MgAlON solid solution and the contents of AlN and MgO, the phase boundaries of MgAlON/(AlN+MgAlON) in MgO-AlN-Al2O3 ternary system at 1600℃ and 1700℃ were precisely determined.
