Two processing methods have been used to prepare different green compacts of high‐purity BaTiO 3 . The substructures of agglomerates have been examined by SEM, and the strength of the agglomerates was interpreted in a plot of the logarithm of the pressure versus the relative density, which is consistent with the structures of cut surfaces of green compacts. The Hg‐penetration results have been used to compare the uniformity of the powder compacts. The wer method (wet milling and subsequent wet pressing) was used to produce uniform green compacts.
