Abstract
Ceramic precursor compositions, such as metal hydroxides and oxides, are electrochemically deposited in a biased electrochemical cell. The cell typically generates hydroxide ions that precipitate metallic or semimetallic ions to form insoluble solids that may be separated from the cell, then dried, calcined and sintered to form a ceramic composition.
