Abstract:
1. A ceramic powder composition, comprising a main component, comprising (Ba1-xCax)mTiO3+αMgO+βRe2O3+γMnO+δB2O5, wherein α, β, γ and δ are molar ratio constants, and 0.1≦α≦3.0, 0.05≦β≦3.0, 0.001≦γ≦0.2, and 0.0<δ≦0.1; 0.99≦m≦1.030, and 0.005≦x≦0.015; element Re is selected from a group consisting of yttrium (Y), chromium (Cr), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), and ytterbium (Yb); and element B is selected from a group consisting of vanadium (V), niobium (Nb), and tantalum (Ta); and a glassy component, having a content of 0.2-2.0 mole % based on the main component, and comprising (Ba
