Ammonia
chemical formula NH3, ammonia is a toxic gas with a TLV of 25ppm, and is combustible in the range of 12-28%. Ammonia has a strong pungent odor and is irritating to lungs, skin and eyes. Ammonia is commonly used as a deposition gas for silicon nitride, Si3N4 and may also be used to anneal titanium, Ti, to form titanium nitride, TiN or to anneal gate oxides to form oxynitride, SixOyNz.

AMMONIA
A form of nitrogen found in organic materials, sewage, and many fertilizers. It is the first form of nitrogen released when organic matter decays. It can be used by most aquatic plants and is therefore an important nutrient. It converts rapidly to nitrate (NO3) if oxygen is present. The conversion rate is related to water temperature. Ammonia is toxic to fish at relatively low concentrations in pH-neutral or alkaline water. Under acid conditions, non-toxic ammonium ions (NH4+) form, but at high pH values the toxic ammonium hydroxide (NH4OH) occurs. The water quality standard for fish and aquatic life is 0.02 mg/l of NH4OH. At a pH of 7 and a temperature of 68 Deg. F (20 Deg. C), the ratio of ammonium ions to ammonium hydroxide is 250:1 at pH 8, the ratio is 26:1. Ammonia is an important aquatic plant nutrient because it is readily available.

Ammonia (NH3)
A pungent colorless gaseous compound of nitrogen and hydrogen that is very soluble in water and can easily be condensed into a liquid by cold and pressure. Ammonia reacts with NOx to form ammonium nitrate -- a major PM2.5 component in the Western United States.

Ammonia
Ammonia is a compound with the formula NH3. It is normally encountered as a gas with a characteristic pungent odor. Ammonia contributes significantly to the nutritional needs of the planet as a precursor to foodstuffs and fertilizers. Ammonia, either directly or indirectly, is a building block for the synthesis of most pharmaceuticals. Although it is in wide use, ammonia is caustic and hazardous.
