seeba Fact Sheet
Arsenic: Cas Number 7440-38-2

 

The fact sheet is generated by materials/substance legislation compliance software produced by PlesTech Ltd.,

 

Substance: Arsenic (As) - Non-metal

 

Substance Properties:

Atomic / Molecular weight = 74.92
Density = 5.72 gm/cc
Melting temperature = 808°C
Boiling point = 603°C
Specific heat = 0.0785 cal/°C at 20°C

 

Toxicity

Toxic carcinogen. Poisonous and at at high levels can cause death. At lower levels can cause nausea and
vomiting, abnormal heart rhythm, reduced production of red and white blood cells, and damaged blood
vessels. Prolonged exposure to lower levels can cause a discoloration of the skin and the appearance of
small corns or warts. Inorganic arsenic is considered more toxic than organic arsenic

When used as gallium arsenide it is not toxic


Applications

Arsenic is used as dopant in semiconductor manufacture. Gallium arsenide is used as semiconductor
substrate. Other uses include lasers, light-emitting diodes (LED), paints, fusion coating, wood
preservatives, leather and textile finnishers, water treatment agents, flat glass, metal adhesives,
pyrotechnic objects, metal refinement, impregnation of wood.
