RuO2

Ruthenium dioxide (RuO2) is a ceramic oxide compound prized for its electrical conductivity and electrochemical stability—unusual among traditional ceramics. It is widely employed in electrodes for electrochemical cells, as a catalyst support in chemical processing, and in resistive heating elements where thermal stability and electrical performance must be balanced. Engineers select RuO2 when they need a material that combines ceramic durability with metallic-like conductivity, particularly in harsh electrochemical or high-temperature environments where conventional conductors would degrade.
