Abstract

See full text

An ink of the formula: 60-80% by weight BaTiO3 particles coated with SiO2; 5-50% by weight high dielectric constant glass; 0.1-5% by weight surfactant; 5-25% by weight solvent; and 5-25% weight organic vehicle. Also a method of manufacturing a capacitor comprising the steps of: heating particles of BaTiO3 for a special heating cycle, under a mixture of 70-96% by volume N2 and 4-30% by volume H2 gas; depositing a film of SiO2 over the particles; mechanically separating the particles; incorporating them into the above described ink formulation; depositing the ink on a substrate; and heating at 850-900° C. for less than 5 minutes and allowing the ink and substrate to cool to ambient in N2 atmosphere. Also a dielectric made by: heating particles of BaTiO3 for a special heating cycle, under a mixture of 70-96% by volume N2 and 4-30% by volume H2 gas; depositing a film of SiO2 over the particles; mechanically separating the particles; forming them into a layer; and heating at 850-900° C. for less than 5 minutes and allowing the layer to cool to ambient in N2 atmosphere.
