Ruthenium has a variety of uses. Of course, as one of the rare metals, it is also one of the indispensable metal elements for industrial use. Ruthenium is a hard, brittle and light gray multivalent rare metal element, which is one of the platinum group metals. a member. Therefore, ruthenium is a precious metal element used in industry, and it is also one of the indispensable metal elements.

When the temperature reaches 100 ℃, it has resistance to various acids including aqua regia, and also has resistance to hydrofluoric acid and phosphoric acid. At room temperature, iodine in chlorine water, bromine water and alcohol can corrode ruthenium slightly. Resistant to many molten metals including lead, lithium, potassium, sodium, copper, silver and gold. Works with molten alkaline hydroxides, carbonates and cyanides.
Ruthenium series resistor paste: the most widely used resistor paste composed of electrically conductive materials (ruthenium dioxide, bismuth ruthenate, lead ruthenate, etc.), glass binder, organic carrier, etc. It has the advantages of low temperature coefficient, good resistance reproducibility, and good environmental stability, and is used to make high-performance resistors and high-reliability precision resistor networks.
