  • Industrial uses, in fungicides, and also is contained in Mica powder
  • Mica powder is used in waterproof paint pearl, pigments, and lubricants.

interesting facts

Whats It made of?

  • Typically confused with mercuric Oxide, which is a reddish orange powder.
  • If mixed with phosphorous or sulfur it can cause an explosion. phosphorous- caused by impact; sulfur- caused by friction.

Toxicity

  • Mercurous Oxide is composed of Mercury and Oxygen or Hg2O. More specifically it is made of two units of Mercury and one unit of oxygen.
  • A very toxic substance, it is considered a poison
  • the exposure limit; IDLH: 10 mg/m3
  • side affects of exposure: tremor, confusion, loss of coordination, hyperreflexia
  • Has a Hazard class of 6.

  • Also Known as Mercury Oxide, Mercury I Oxide, or Mercury Oxide black. It is a black, or brownish black powder.
  • Not to be confused with Mercuric Oxide or Mercury II Oxide.

Properties

  • Mercurous oxide is a denser thank water with a density of 13.6 g/cm3
  • It is insoluble in water, but is soluable in other things such as nitric acid.
  • Highly Toxic
  • Non-combustible

Hows it made?

  • Technically not a true compound because it is made from the compound Mercuric oxide (HgO) and Mercury.
  • However it can occur naturally if mercury is in moist air, which may cause it to oxidize into a film of mercurous oxide.
