Hexagonal type barium titanate powder, producing method thereof, dielectric ceramic composition and electronic component
摘要:
Dielectric ceramic composition includes a hexagonal type barium titanate as a main component shown by a generic formula of (Ba1-αMα)A(Ti1-βMnβ)BO3 and having hexagonal structure wherein an effective ionic radius of 12-coordinated “M” is −20% or more to +20% or less with respect to an effective ionic radius of 12-coordinated Ba2+ and the A, B, α and β satisfy relations of 1.000
