HIGH FREQUENCY DIELECTRIC CERAMIC COMPOSITIONS FOR LOW TEMPERATURE SINTERING AND FABRICATING METHOD THEREOF, AND DIELECTRIC COMPONENTS USING THE SAME

摘要

This invention relates to a high-frequency dielectric composition and a method of manufacturing a dielectric component for high frequency using the same low-temperature sintered by general formula Ba (Mg _1/3 Nb _2/3 ) O ₃ -xB ₂ O ₃ -yCuO displayed as [BMN-B-Cu] and , B for the entire composition ₂ O ₃ molar fraction of the and CuO , respectively 2.0mol% x 30.0mol%, and 0.5mol% y has a value in the range of 30.0mol%. ; in the present invention generally have a high dielectric constant ( _r ) and quality factor (Q f), and -14 ~ -3.11ppm / in the range of the resonant frequency temperature coefficient with ( _{have a f} ) , the temperature of the sintering process of this dielectric composition is a high-frequency dielectric composition having excellent properties , so that the sintered ceramic can be used as part of a multi-layer high-frequency dielectric material at 850 .
