RUTHENIUM ACID BISMUTH PARTICLE CONTAINING GLASS, METHOD FOR MANUFACTURING THE SAME, THICK FILM RESISTOR COMPOSITION AND THICK FILM RESISTOR PASTE

摘要

PROBLEM TO BE SOLVED: To provide ruthenium acid bismuth containing glass obtained by depositing ruthenium acid bismuth having a crystallite diameter of 20-100 nm in lead-free glass frit as a conductive material for thick film resistors; a method for manufacturing the same; a lead-free resistor composition using a powder of the glass; and thick film resistor paste using the thick film resistor composition.;SOLUTION: In the ruthenium acid bismuth containing glass, ruthenium acid bismuth particles shown by the general formula (Bi_2+XRu₂O_7+Y, where X=-0.13 to 0 and Y=-0.5 to +0.4) exists in the glass. The half-value width of (111) planes of the ruthenium acid bismuth particles by the X-ray diffraction measurement of the glass is in a range of 0.16-0.48°, and a crystallite diameter required from the half-value width is 20-100 nm.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
