Abstract
The present invention relates to a variety of dispersible doped multi-component BaTiO.sub.3 based powder compositions. The primary particles of each of the products are substantially spherical, have sizes in the range of 0.05 to 0.4 microns and have narrow size distributions. Further, the compositions of the primary particles, forming each powder, are comparable. The amount of dopant oxide or oxides contained in the powder composition ranges from between greater than 1 to 10 mole percent. Regardless of the dopant or dopants utilzied, all the powder compositions of the present invention are identified by the same unique morphological characteristics.
