Abstract
Methods for manufacturing a powder of a dielectric compound include mixing particle components that are combinable to form the dielectric compound with matrix components. The mixture is melted, and the molten mixture is quenched to produce a solid material. The dielectric power is extracted from the solid material. A molar ratio of particle components to matrix components can be selected so that the solid material produced by quenching is amorphous. Particle components can be selected to produce Ba1−xSrxTiO3 powder, wherein 0≦x≦1. Matrix components consist essentially of Na2O·2B2O3 and Na2O·SiO2·9H2O or can be selected from a group consisting of zinc oxide, zinc carbonate, and zinc hydroxide.
