Ruthenium powder is a powder material made from high-purity ruthenium metal through fine processing, which plays an irreplaceable and important role in the fields of electronic slurries and catalysis. In the field of resistive slurries, ruthenium powder and its oxides are dispersed as conductive functional phases in glass bonding phases, and a dense resistive film layer is formed on the surface of ceramic substrates through screen printing and sintering processes. They are used to manufacture electronic components such as chip resistors, thick film resistor networks, and precision electrical contacts. Ruthenium based resistor paste has the characteristics of wide resistance range, low temperature coefficient of resistance, and excellent long-term stability, making it the core material of high-performance thick film resistor components.
In the field of catalysis, ruthenium powder is formulated into an efficient catalyst slurry and coated on the surface of a carrier to form a catalytic active layer. The high catalytic activity and chemical stability of ruthenium make it play a key role in environmental protection fields such as chemical synthesis catalytic reactions, petroleum refining hydrogenation desulfurization, and exhaust gas purification. Ruthenium exhibits excellent catalytic selectivity for various chemical reactions, significantly improving reaction efficiency and product yield.
The core advantages of this product are: excellent conductivity and catalytic activity, stable physical and chemical properties; The particle size and morphology can be customized to meet the dispersion and sintering process requirements of different slurry systems; Widely used in the manufacturing of electronic components such as chip resistors and electrical contacts, as well as in catalytic fields such as chemical synthesis and petroleum refining, it is an indispensable key precious metal material in high-tech and industrial fields.
