These glass ceramics are produced in a two-step process. In a first step a transparent glass with a solely amorphous structure is molten. In a second and independent step crystallites are grown in such glasses by applying a well defined time-temperature profile. By growing nanosized crystallites with ferro- or para-electric phases, pore free dielectric materials with very high homogeneity and high dielectric strength are obtained. In the current paper we present two types of such material. The… CONTINUE READING
