3960 results about "Asbestos" patented technology

Asbestos (pronounced: /æsˈbɛstəs/ or /æsˈbɛstɒs/) is a term used to refer to six naturally occurring silicate minerals. All are composed of long and thin fibrous crystals, each fiber being composed of many microscopic 'fibrils' that can be released into the atmosphere by abrasion and other processes. Asbestos is a well known health hazard, and use of it as a building material is now banned in many countries. Inhalation of the fibres can lead to various lung conditions, including asbestosis and cancer.
