  • Process for the manufacture of a capacitor dielectric with inner blocking layers
    Patent number: 4148853
    Abstract: For the manufacture of a dielectric with inner blocking layers on the basis of barium titanate smooth fragments, that is a finely ground material after sintering whose composition is equal to or approximately equal to the composition of titanate powder, is added to the titanate powder, which is then transformed through pre-baking before pressing of the desired solids. The addition of such smooth fragments reduces the tolerance on electrical parameters of the dielectric.
