4. Uses
•Arsenic is used as a doping agent in semiconductors (gallium arsenide)
for solid-state devices. It is also used in bronzing, pyrotechnics and for
hardening shot.
•Arsenic compounds can be used to make special glass and preserve
wood.
•As a result of its toxicity, arsenic compounds are used in wood
preservation and insecticides.
•Gallium arsenide (GaAs) is a semiconductor used in laser diodes and
LEDs.
•Small amounts of arsenic (less than two percent) can be used in lead
alloys for ammunition.
•Despite its potential toxicity, arsenic is also an essential element,
necessary to our physiology. A level of 0.00001% is needed for growth
and for a healthy nervous system.
7. Arsine
•Arsine is a colorless,
flammable, non-irritating
toxic gas with a mild garlic
odor. Arsine is formed
when arsenic comes in
contact with an acid.
•Arsine is similar to a gas
called stibine, which is
formed when the metal
antimony comes in contact
with an acid. Stibine has
health effects similar to
those of arsine, but it is not
as widely available, and it
has a much more
noticeable “rotten-egg”
odor.
8. Arsine applications
• Arsine is used extensively in the manufacture of
microchips.
• Arsine is used most commonly in the semiconductor
and metals refining industries.
•Electronic Grade Arsine Gas
•Technical Grade Arsine Gas
•Solar Battery
•Polysilicon
•Semiconductors
