High dielectric constant buried capacitors with extended operating temperature ranges
 Various mixtures of lead magnesium niobate and lead titanate are made, each mixture having a different Curie temperature, wherein these mixtures are mixed together to form capacitor inks that can be used to make capacitors embedded in multilayer ceramic circuit boards. These capacitors have extended temperature ranges of operation as well as low loss tangents and high dielectric constants.
