Ruthenium resistor paste: electric conductance material (ruthenium, ruthenium dioxide acid bismuth, ruthenium lead acid, etc.) glass binder, the organic carrier and so on of the most widely used a resistor paste, with a wide range of resistance, low temperature coefficient of resistance, resistance with good reproducibility, and the advantages of good environmental stability, used to make high performance resistance and high reliable precision resistor network.
Ruthenium pellet is often used as element additives for the manufacture of Ni-base superalloy in aviation and industrial gas turbine. Research has shown that, in the fourth generation of nickel base single crystal superalloys, the introduction of the new alloy elements Ru, which can improve the nickel-base superalloy liquidus temperature and increase the alloy's high temperature creep properties and structural stability, resulting in the special "Ru effect" to improve overall performance and efficiency of the engine.
