摘要
Porometry and scanning electron microscopy were employed to examine the microstructure in barium zirconate and barium cerate samples synthesized using cryochemical freeze drying or spray drying. Intergrain pores in these samples have been found to have surface fractality. The fractal dimension ranges from 2.07 to 2.24; the self-similarity range reaches one order of magnitude.
