seeba Fact Sheet
Mercury : Cas Number 7439-97-6

 

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

Substance: Mercury (Hg) - Metal


Physical Properties

Appearance: Liquid metallic silver
Atomic / Molecular weight = 200.59
Density = 13.546 gm/cc
Melting temperature = -38.83°C
Boiling point = 356.73°C
Specific heat = 0.033 cal/°C at 20°C
Resistivity = 0.964 ohms-mm2 / m at 20°C
Mercury is normally economic to recycle


Toxicity

Neurotoxin. Absorbed via respiratory tract as elemental mercury vapor, mercury compound dust
Short-term exposure to high levels of metallic mercury vapors may cause lung damage, nausea, vomiting,
diarrhea, increases in blood pressure or heart rate, skin rashes, and eye irritation.

High levels of metallic, inorganic, or organic mercury can permanently damage the brain, kidneys, and
developing fetus. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision
or hearing, and memory problems.


Applications

Mercury is used in electrical switches, electric rectifiers, batteries, thermostats, accumulators, high density
discharge lamps, back lights for LCDs and anti-fouling paints.
