Abstract: Dielectric behaviour of hot pressed aluminium nitride (AIN) ceramic with and without additives is studied before and after exposing the samples to some inorganic and organic acid vapours. It is observed that the dielectric dispersion increases after exposing the samples to acid vapours over and above the atmospheric humidity. In all the cases the presence of oxide additives (BeO, MgO, and Y2O3 is found to increase the exposure effects.
