Abstract: A formulation comprising, by weight, 4.7-39.7 percent polymethylmethacrylate (PMMA), 0-9.1 percent plasticizer and 60.3-93.0 percent dielectric glass (along with an appropriate amount of solvent) is ball milled to an appropriate size for spraying. After the formulation is sprayed onto a substrate, it is baked at a temperature of approximately 620 DEG C. for approximately 2 hours. During the baking step, the PMMA decomposes to a methylmethacrylate monomer. The resultant dielectric coating will contain a small amount of residue (less than 1 percent) of the monomer and the plasticizer.

Abstract: Production of a sintered ceramic dielectric formed from a green sheet having a uniform microporous structure providing uniform dielectric properties and compressibility for lamination of stacked green sheets into a unitary laminate which may be provided with an internal pattern of electrical conductors extending therein. The structure is obtained by blending the ceramic particulate in a solution of a binder resin miscible in a solvent mixture which is formed from a volatile solvent for the binder resin and a less volatile solvent in which the resin is at most only slightly soluble.
