Dielectric ceramic composition for low temperature sintering and multiplayer ceramic chip capacitor produced using the composition

摘要

The present invention relates to a dielectric ceramic composition. The dielectric ceramic composition _{aBaTiO 3 -bMgCO 3 -cY 2 O 3} -dCr 2 O 3 -eV 2 O 5 - f (xZrO 2 -y (K, Li) 2 O-zSiO 2) ( proviso that x + y + z a = 1 0.05≤x≤0.18, 0.01≤y≤0.08, and 0.74≤z≤0.93 composition in a), the molar ratio to a = 100, 1.0≤b≤2.0, 0.2≤ c≤2.0, 0.02≤d≤0.3, 0.02≤e≤0.3, satisfies 0.5≤f 2. The multilayer ceramic capacitor using the dielectric ceramic composition is also provided. In the present invention, it is possible by the low temperature firing is possible without lowering of the dielectric constant to the dielectric thin layer by second.
