FAR specializes in fine and specialty chemicals such as brominated compounds, organometallics,
pyrophoric materials, and the distribution of trimethylchlorosilane.
There are two possible sources of ignition - static electricity generated in the hose being used for pumping or the presence of
pyrophoric substances in the tank, which can spontaneously combust on contact with air.
However, these bring different challenges as they are energetic and extremely air and moisture sensitive, and often necessitate the use of
pyrophoric and short shelf-life reagents.
The tank had been emptied and flushed as per standard operating procedures, and was in the initial stages of venting to remove
pyrophoric material which likely became flammable, causing the fire, it added.
Some materials are
pyrophoric (they ignite easily when coming into contact with air).
for REE imports are free for lanthanum oxides and other oxides, and range from 3.7% for lanthanum carbonates, other carbonates, and other REE compounds; 5% for scandium and yttrium whether or not mixed or intermixed; 5.5% for cerium compounds such as oxides; and 5.9% for ferrocerium and other
pyrophoric allies.
Gregite ([Fe.sub.3] Iron Sulfide Corrosion Products: [S.sub.4]) Pyrite (Fe[S.sub.2]) (i)
Pyrophoric iron sulfide Marcasite (Fe[S.sub.2]) (pyrrhotite-FeS) results from Mackinawite (Fe[S.sub.0.9]) the corrosive action of sulfur Pyrrhotite ([Fe.sub.7] or sulfur compounds [S.sub.8]) ([H.sub.2]S) on the iron (steel) and moisture.
These materials are not toxic or
pyrophoric, and their cost is lower than previous materials used in CdSe QD synthesis.
TEA-TAB is
pyrophoric, meaning it spontaneously catches fire when exposed to your run of the mill air, a decidedly human-unfriendly feature.
RIYADH: Saudi Aramco's Haradh Gas Plant has pioneered the use of Concrete Canvas (CC) in the construction of a
pyrophoric treatment area, the works for which were carried out by Saudi-based Freih Bin Owaidha Al Qahtani Sons Co Ltd (FOQSCO).
A chemical that is
pyrophoric (UN GHS Hazard H250) is also a flammable liquid (UN GHS Hazard H228).
It's not truly
pyrophoric; that distinction belongs to much lighter methyl-metallics like dimethylzinc and trimethylaluminum.
