Abstract

The present process is a process for preparation of crystalline grains-oriented ceramics which comprises orienting grains of ceramics raw material powder to a definite direction by applying centrifugal force on the grains and then burning the resulting grains. These ceramics are expected to be utilized, for example, as .beta.- or .beta."-alumina solid electrolytes for use in sodium-sulfur cells and as magnetic anisotropic ferrite magnets for use in small-sized motors, speakers or the like.
