Mercury oxide is used in the production of mercury cathode batteries.
Mercury oxide is also used to make and produce different pigments.
This oxide is also widely used in the production of mercury-based super media.
This substance is used as a very powerful disinfectant and germ killer.
It can be used in the production of mercury metal, because mercury oxide is easily decomposed and when it is decomposed, oxygen gas is produced.
Other applications include the use as a catalyst or detector in animal feed to detect the presence of zinc, hydrogen cyanide, acetic acid, formic acid and carbon monoxide in a gaseous mixture.
