A low temperature sinterable dielectric ceramic composition and a multilayer ceramic chip capacitor. The dielectric ceramic composition is expressed by the general formula: aBaTiO3-bMgCO3-cY2O3-dCr2O3-eV2O5-f(xZrO2-y(K,Li)2O-zSiO2) (x+y+z=1; 0.05<=x<=0.18, 0.01<=y<=0.08, and 0.7.4<=z<=0.93); in which a, b, c, d, e and f are molar ratios; a=100, 1.0<=b<=2.0, 0.2<=c<=2.0, 0.02<=d<=0.3, 0.02<=e<=0.3, and 0.5<=f<2. The multilayer ceramic chip capacitor is prepared using the dielectric ceramic composition. The dielectric composition according to the present invention can be sintered at a low temperature without decrease of a dielectric constant, making it possible to make ultra thin-layered dielectrics.
