ABSTRACT This invention relates to a process of freezing an inorganic particulate or a ceramic slurry containing a freeze sensitive ceramic colloidal sol including regulating or adjusting the relative zeta potentials of the particulate particles and the sol particles to cause the sol particles to precipitate onto the surface of the particulate particles during the mixing of the particles. The invention includes the addition of lithium ions to the freezing media with or without supercooling. The invention further includes composite inorganic structures which are in the nature of laminates where at least one inorganic structure, such as a zirconia plate, is adhered to a different inorganic structure, such as an alumina plate.
