  • Method for reduction of sinter temperatures of antiferroelectric, lead-based ceramics by use of lithium compound additions and capacitors made with such ceramics
    Patent number: 5993895
    Abstract: A method for densifying a dielectric antiferroelectric material includes the steps of adding a compound which includes lithium to the dielectric material to create a mixture thereof. Thereafter, the mixture is heated to a temperature of not greater than about 1100.degree. C. for a predetermined period to densify the mixture. It is preferred that the lithium compound be a lithium salt and that the dielectric material comprise a PLZT composition.
