ACUTE HEALTH EFFECTS

 

Swallowed:

 

Will cause severe irritation to the mouth, mucous membranes, throat, oesophagus

 

and stomach. May result in difficult breathing, stomach pain and circulatory shock.

 

Toxic if swallowed.

 

Due to acid in the stomach, hydrofluoric acid will be released with systemic fluoride

 

poisoning likely with severe and potentially fatal hypocalcemia.

 

 

Eye:

 

Will cause severe irritation to the eyes, with effects including: tearing, pain, and

 

stinging. Depending upon duration of exposure, eye damage may occur.

 

 

Skin:

 

Will cause irritation to the skin, with effects including; redness, itchiness, and

 

possible dermatitis.

 

 

Inhaled:

 

Dusts may cause irritation to the nose, throat and respiratory system with effects

 

including: coughing, choking. In severe cases, inhalation may result in spasm,

 

inflammation and edema of the larynx and brochi, chemical pneumonitis and

 

pulmonary edema. Extremely destructive to tissue of the mucous membranes and

 

upper respiratory tract.

 

 

Chronic:

 

This product may cause severe eye irritation and depending upon duration of

 

exposure, some form of permanent eye damage may occur. Prolonged or repeated

 

skin contact may lead to dermatitis. Exposure to fluorides is associated with

 

fluorosis. Kidney damage, asthma and rheumatism symptoms may occur if

 

exposure standards are exceeded. Chronic effects include excessive calcium

 

precipitation by the fluoride ion in the bones, ligaments and tendons. Prolonged or

 

repeated skin contact will lead to necrosis (death) of the skin.

Aluminium Industry

 
Inorganic fluorine compounds play an outstanding role in the aluminum industry.
 
They are frequently encountered not only in the manufacture, but also in the
 
processing and finishing of aluminum.
 
The manufacture of aluminum on a commercial scale was first made possible with
 
the introduction of cryolite at the end of the 19th century. Cryolite as the essential
 
component of the electrolyte (85 – 90 %) decreases the temperature of the smelting
 
flux electrolysis.
 
Other important additions to electrolytes in current commercial use are aluminum
 
fluoride, calcium fluoride and lithium fluoride. These fluorides increase the
 
conductivity of the electrolyte and improve the efficiency of the used energy. The
 
aluminum so produced has a purity of between 99.5 and 99.9 %. Refining, that is to
 
say the thorough cleaning and improvement of aluminum, is carried out for example
 
by a process of three-layer fused-salt electrolysis. This method represents the only
 
commercially viable process for the production of pure aluminum. Further
 
electrolyte components from our product range which may be used are barium
 
fluoride or calcium fluoride. Aluminum produced by this method has a purity of
 
between 99.99 and 99.999 %.
