1) W. J. Tropf and M. E. Thomas, Magnesium aluminum spinel (MgAlO 4), in E. D. Palik (ed. According to formula MgAl2O4 oxygen contains 4 atoms that means it is forming CCP or FCC also there is only 1 mg atom and 2 Al atom.Z=4Octahedral voids=4Tetrahedral voids=8As mg is occupying tetrahedral voids so percentage = (1/8)×100=12.5%.And percentage of octahedral voids occupied by Al atoms=(2/4)×100=50%. The sintering kinetics of a pure magnesium aluminate spinel, MgAl2O4, and that doped with LiF were determined through the use of the master sintering curve technique developed by Su and Johnson. 20 Powders with 0%, 0.5%, and 1.0% by mass LiF were densified in a vacuum hot press under a range of unaxial pressures. Given this resilience, the likelihood of radi- ation induced swelling and microcrack formation is dramatically supressed. keertanachiguru3581 27.04.2018 Chemistry Secondary School +13 pts. U. Anderson—contributing editorPlease check your email for instructions on resetting your password. 1 illustrates the arrangement of the Mg (Zn), Al and O atoms in a unit cell of normal spinel [15,16]. Magnesium aluminate (MgAl2O4) spinel has demonstrated a strong resis- tance under irradiation to the formation of large defect aggregates such as dislocation loops and voids. It suggests that the Al 3+ cations can occupy more than one position in the structure and the site … The classic example is MgAl2O4 where Mg is the M(II) cation and Al the M(III) cation.

According to formula MgAl 2 O 4, if there are 4 oxide ions then the compound will contain 1 Mg +2 ion and 2 Al +3 ions.. Now, for 4 O-2 ions in ccp arrangement, there will be 4 octahedral voids and 8 tetrahedral voids, so. X.L. Since, Mg 2+ ion is in tetrahedral field and Al +3 ion is in tetrahedral field, so the spinel is a normal spinel..
