The Preparation of Laminated Ceramic Composites Using Paint Technology
Ceramic paints comprising ceramic powder, dispersant, resin and solvent were prepared by high speed mixing. The powders were alumina and alumina with 20 vol % zirconia. Alternate layers of paint having thicknesses of 20-30 mu m were deposited by the random deposition of droplets from a conventional paint spray gun operating on compressed air. Laminates of up to 1 mm were produced. The microstructure of the multilayer ceramic wafers produced by drying, thermolysis and sintering is reported. The method avoids the thermolamination step associated with tape casting and allows laminates to be prepared on contoured fugitive substrates.
