Aqueous precipitation in a computer-controlled continuous crystallizer has been applied to the preparation of cordierite, mullite, alumina, and zirconia precursor powders. The particles are dense, spherical, and x-ray amorphous. The powders have a particle size range of 0.2–5 μm and a surface area of 1 – 10 m2/g The properties of the powders and of some green and fired pieces are described.
