Dielectric porcelain composition for high frequency, dielectric resonator, dielectric filter, dielectric deyupurekusa, and transmitter device

摘要

Using in the high frequency territory of microwave and ultra high frequency etc, _r and Q value are high, in addition that the absolute value _f is small, the dielectric porcelain composition for high frequency whose calcination at temperature below the 1400C which is sufficiently lower than past in addition to possessing the induced electricity quality whose you said, is superior, is possible is offered. Composition formula: (1-y) xCaTi _aO1+2a- (1-y) (1-x) Ca (M1 _z/3 M 22_/3) _{bO1+2b-yLnAl cO (3+3c)/2} (however, x, y mol ratio) with to have the constitution which is displayed, when = (1-y) making x, x in the above-mentioned composition formula, y, z, a and b, c and , converting the secondary component which is B chemical compound vis-a-vis the main component 100 weight section which is inside the range of each one 0.56x0.8, 0.08y0.18, 0.980z1.000, 0.65, 0.985a1.05, 0.9b1.02 and 0.9c1.05, to B₂ O_3, 0.005 - 0.300 weight sectionsIt contains.
