Crocidolite, commonly known as blue asbestos, is a naturally occurring mineral that belongs to the amphibole group of silicate minerals. It is characterized by its blue color and fibrous structure, which makes it highly heat-resistant. Crocidolite was widely used in various industrial applications, including insulation, roofing, and cement products, due to its durability and fire-resistant properties. However, crocidolite is also known for its health risks. Inhalation of its fine fibers can lead to serious respiratory diseases, including asbestosis and lung cancer. As a result, the use of crocidolite has been banned or heavily regulated in many countries, reflecting growing awareness of the dangers associated with asbestos exposure.
