Ruthenium(IV) oxide is the inorganic compound with the formula Ru O 2. This black solid is the most common oxide of ruthenium . It is widely used as an electrocatalyst for producing chlorine, chlorine oxides, and O 2 . [ 1 ]
Distrontium ruthenate, also known as strontium ruthenate, is an oxide of strontium and ruthenium with the chemical formula Sr 2 RuO 4.It was the first reported perovskite superconductor that did not contain copper.

The fluorescence of some ruthenium complexes is quenched by oxygen, finding use in optode sensors for oxygen. [65] Ruthenium red , [(NH 3 ) 5 Ru-O-Ru(NH 3 ) 4 -O-Ru(NH 3 ) 5 ] 6+ , is a biological stain used to stain polyanionic molecules such as pectin and nucleic acids for light microscopy and electron microscopy .

Ruthenium can be oxidized to ruthenium(IV) oxide (RuO 2, oxidation state +4), which can, in turn, be oxidized by sodium metaperiodate to the volatile yellow tetrahedral ruthenium tetroxide, RuO 4, an aggressive, strong oxidizing agent with structure and properties analogous to osmium tetroxide.
If the process requires a very fast response to temperature changes (fractions of a second as opposed to seconds), then a thermocouple is the best choice. Time response is measured by immersing the sensor in water moving at 1 m/s (3.3 ft/s) with a 63.2% step change. Size

Ruthenium tetroxide is the inorganic compound with the formula RuO 4. It is a yellow volatile solid that melts near room temperature. [3] It has the odor of ozone. [4] Samples are typically black due to impurities. The analogous OsO 4 is more widely used and better known. It is also the anhydride of hyperruthenic acid (H 2 RuO 5).
