Title:
DIELECTRIC PORCELAIN COMPOSITION FOR HIGH FREQUENCY AND DIELECTRIC RESONATOR
Document Type and Number:
Japanese Patent JP3510948
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition for high frequency having relative permittivity lower than alumina and forsterite, and Q-value higher than glass ceramic and steatite.
SOLUTION: This dielectric porcelain 1 composition for high frequency is a compound oxide comprising Mg and Si as metal elements in which when a molar ratio compositional formula by the oxide of each metal element is expressed by xMgO-ySiO2, the (x, y) satisfy 40≤(x)≤50, 50<(y)$60 and (x+y)=100, and has ≤7 relative permittivity and Q-value ≥2,000 at 10GHz. The composition is used as a porcelain substrate 3 or a supporting member 2 of a dielectric resonator.
