Abstract
An additive that contains an emulsion binder resin substantially free of non-emulsion binder resin, such as an emulsion acrylic resin, is mixed into a ceramic raw material powder containing, as its main constituent, a perovskite-type compound to form a ceramic slurry. Then, an orientational ceramic is prepared by subjecting the slurry to a forming process while simultaneously or sequentially applying a magnetic field and drying the slurry. An orientational ceramic, even formed from a substance which has small magnetic anisotropy, such as PZT, is obtained.
