The relative frequencies of pore location on grain corners, edges, and surfaces in final stage sintering have been measured in both pure and MgO‐doped Al 2 O 3 . Both materials showed identical location frequencies, with an average of 58% of the pores on grain corners, 29% on grain edges, and 13% on grain surfaces, over a density range from 92% to > 99% of full density.
