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 τfof resonance frequency and a dielectric constant εrof about 20-70 to form a multilayer ceramic component, etc., of a moderate size. SOLUTION : The composition contains 5-150 pts.wt. glass component against 100 pts.wt. essential component of the formula : xZn2TiO4-yZnTiO3-z(lBaO-mTiO2-nR2O3) (wherein x, y, z, l, m and n each satisfies 0COPYRIGHT : (C)2004, JPO |
