Ruthenium oxide powder, thick-film resistor-body composition using the same, thick-film resistor paste and thick-film resistor

摘要

chip resistor having a sufficient performance even at low ruthenium content, hybrid IC, or ruthenium oxide powder which can be inexpensively manufactured as an electronic component material, such as a resistor network, to provide a thick film resistor-body composition and thick film resistor using the same. A ruthenium oxide (RuO2) powder having a rutile crystal structure, a crystallite diameter thereof was measured (110) plane in X-ray diffraction method 3~10nm, and Ru content is 73 mass% or more ruthenium oxide powder, characterized in that; thick film resistor-body composition formed by blending the conductive particles and the glass powder of ruthenium oxide powder as a major constituent; thick film resistor composition is an organic vehicle in containing the fatty acids A dispersed thick film resistor paste, and provided by such thick-film resistor paste and the content of the fatty acid is 0.1 to 10 parts by weight based on ruthenium oxide 100 parts by weight.
