Abstract

Barium titanate powder was CIPed under 1.0 GPa repeatedly up to 60 times. The crystallite size decreased and lattice strain increased with CIPing times. However, the specimen was characterized to belong to the tetragonal phase even after CIPed 60 times. The integrated diffraction intensity of barium titanate was revealed to increase notably by CIPing. The tweedy and/or squeezed texture was analyzed having collapsed boundary zones and modulated array of lattice.
