Title:
DIELECTRIC PORCELAIN COMPOSITION
Document Type and Number:
Japanese Patent JPH08208329
Kind Code:
A
Abstract:
PURPOSE: To obtain a dielectric porcelain compsn. having a high relative dielectric constant r, a high no-load Q value and a low temp. coefft. τf of resonance frequency and capable of sintering at a low temp.
CONSTITUTION: The principal component of this dielectric porcelain compsn. is represented by the compositional formula xBaO-yTiO2-zNd2O3-tSm2O3 (0.1≤x≤0.2, 0.5≤y≤0.8, 0.01≤z≤0.2, 0≤t≤0.2 and x+y+z+t=1) and consists of barium, titanium, neodymium, samarium and oxygen, and this compsn. contains PbO-ZnO-B2O3 glass powder, GeO2 and MgO as secondary components. The glass powder content is 1-25wt.% of the amt. of the principal component and the GeO2 and MgO contents are 0.5-10wt.% and >0 to <5wt.%, respectively.
