Selenium Dioxide Properties

Selenium Dioxide

Molecule Structure Image



Selenium dioxide is one of the most frequently encountered compounds of selenium. It is an important reagent in organic synthesis. It imparts a red colour to glass: it is used in small quantities to counteract the blue colour due to cobalt impurities and so to create colourless glass. In larger quantities, it gives a deep ruby red colour. It is the active ingredient in some cold-blueing solutions. It is also used as a toner in photographic developing.
