Abstract :
In this study, gamma ray transmission method have been used to determine the t otal porosity in four samples: pure Alumina ( Al2O3 ), Al2O3 + (0.2wt%)MgO , Al2O3 + (0.6wt% )Y2O3 and Al2O3+ (8wt% ) ZrO2 . T he experimental setup for the gamma ray transmission consist of 13 7Cs gamma source ( 662 KeV ), a NaI (T l) scint illation detector measured the at tenuation of strongly collimat ed gamma beam through alumina samples. T he porosity obtained by the gamma ray transmission method were compared with the measurements by convent ional (Archimedes) method. It was observed that the porosity measurement by gamma ray transmission method has t he advant age of being accurate, nondestructive and fast analysis.
