Krysotiili

Krysotiili is a mineral belonging to the serpentine group. It is a hydrated magnesium silicate with the chemical formula Mg3Si2O5(OH)4. Krysotiili is characterized by its fibrous structure, which is a key property leading to its widespread use. It is the most common form of asbestos, and historically, it was extensively mined and utilized for its heat resistance, electrical insulation properties, and strength.

The fibers of krysotiili can be very fine and flexible, allowing them to be spun into threads and woven into fireproof fabrics. This made it a valuable material in construction for insulation, roofing, and cement products, as well as in automotive parts like brake linings and clutch facings. However, concerns over the health risks associated with inhaling krysotiili fibers, primarily lung diseases like asbestosis and mesothelioma, have led to significant restrictions and bans on its use in many countries.

Despite the health concerns and subsequent regulatory actions, krysotiili is still produced and used in some parts of the world, particularly in developing nations where regulations may be less stringent or enforcement is weaker. Research continues to explore potential safe uses or methods for managing existing krysotiili-containing materials to mitigate exposure risks. The mineral itself, when not disturbed, does not pose an immediate health hazard. The danger arises when the fibers become airborne and are inhaled.
