<P>PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition which can be baked at 800-1,000°C enabling interpolation and lamination through its simultaneous baking with a low-resistance conductor such as Cu and Ag and has a low dielectric loss tanδ (i.e. a high Q value), a small absolute value of temperature coefficient τ<SB>f</SB>of resonance frequency and a dielectric constant ε<SB>r</SB>of about 20-70 to form a multilayer ceramic component, etc., of a moderate size. <P>SOLUTION: The composition contains 5-150 pts.wt. glass component against 100 pts.wt. essential component of the formula: xZn<SB>2</SB>TiO<SB>4</SB>-y(lBaO-mTiO<SB>2</SB>-nR<SB>2</SB>O<SB>3</SB>) (wherein x, y, l, m and n each satisfies 0<x<1, 0<y<1, 0.10≤l≤0.22, 0.38≤m≤0.8 and 0.17≤n≤0.41, provided that x+y=1 and l+m+n=1; and R is a rare earth element). <P>COPYRIGHT: (C)2004,JPO |
