Document Type and Number:
WIPO Patent Application WO/2013/073295
Kind Code:
A1
Abstract:
[Problem] To provide a dielectric porcelain composition which has a high relative dielectric constant even when calcined at a low temperature and ceramic electronic components in which the dielectric porcelain composition is applied to dielectric layers thereof. [Solution] A dielectric porcelain composition is obtained which comprises: a compound which is represented by general formula ABO3 (A is Ba and at least one type of element selected from Ca and Sr, and B is at least one type of element selected from Ti and Zr) and which has a perovskite crystal structure; and a compound composed of a rare earth titanium oxide which is represented by general formula R2Ti2O7 (wherein element R is at least one type of element selected from Sc, Y, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu).
