DIELECTRIC PORCELAIN COMPOSITION
Document Type and Number:
Japanese Patent JPH0912360
Kind Code:
A
Abstract:
To obtain a dielectric porcelain compsn. of a uniform and very small grain diameter ensuring high density of dielectric porcelain.
Niobium oxide as an accessory constituent is incorporated by 0.3-5.0 pts.wt. (expressed in terms of Nb2O3) into 100 pts.wt. principal compsn. contg. ≤5mol% Bi2O3 based on 100mol% compsn. represented by the general formula xBaO.y[(TiO2)1-s(SnO2)s].zR2O3, wherein R is one or more kinds of elements selected from among La, Pr, Nd and Sm, 0.001≤s≤0.250, (x), (y) and (z) show molar ratio, x+y+z=1 and (x), (y) and (z) are within the range defined by (a) to (e) in the table.
