Method for reduction of sinter temperatures of antiferroelectric, lead- based ceramics by use of lithium compound additions and capacitors made with such ceramics

摘要

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 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.
