Title:
NONREDUCIBLE DIELECTRIC PORCELAIN COMPOSITION
Document Type and Number:
Japanese Patent JP3158567
Kind Code:
B2
Abstract:
PURPOSE: To obtain a nonreducible dielectric porcelain compsn. in which sinters at a low temp. of ≤1,080°C and does not cause the deterioration of the electrical characteristics even by firing in a reducing atmosphere.
CONSTITUTION: This nonreducible dielectric porcelain compsn. contains principal components represented by a general formula A(Bi2O3.BTiO3)+ (100- A)[(Sr100-X-YPbXCaY)TiO3] (where 0≤A≤10mol%, 0.8≤B≤8mol%, 0≤X≤100mol% and 0≤Y≤70mol%) and 0.1-30wt.% secondary components represented by a general formula aLi2O+bRO+cB2O3+(100-a-b-c)SiO2 (where R is at least one among Mg, Ca, Sr and Ba, 0≤a<20mol%, 10≤b<55mol% and 0≤c<40mol%) and further contains 0.01-0.5wt.% MnO2.
