One way to determine a structural defect model (such as that shown in the figure below for a solid solution of Al2 O3 in MgO) is to make careful density measurements.
O2-
AP+
Mg2+
o Vacancy
A substitutional solid solution of Al½O3 in MgO is not as
simple as the case of NiO in MgO. The requirement of charge
neutrality in the overall compound permits only two Al+ ions
to fill every three Mg²+ vacant sites, leaving one Mg²+
vacancy.
What would be the percent change in density for a 5 mol % solution of Al2 O3 in MgO (compared with pure, defect-free MgO)?
Express your answer to three significant figures.
TVo AEO vec
The percent change in density would be
