Mercuric oxide | HgO - PubChem

Hypophosphorous ,acid, reduces ,mercuric oxide, explosively to the metal [Mellor 4:778. 1946-47]. When heated to decomposition (932 F) it decomposes into mercury and oxygen. Fumes from fire may contain poisonous mercury vapor; oxygen may increase intensity of fire. Explosion of ,mercuric oxide, may occur with friction or application of heat.
