Asbestos definition is - any of several minerals (such as chrysotile) that readily separate into long flexible fibers, that cause asbestosis and have been implicated as causes of certain cancers, and that have been used especially formerly as fireproof insulating materials.


Asbestos is resistant to heat, flames, and chemical action. Some forms have been shown to cause lung diseases. For this reason, asbestos is no longer used to make insulation, fireproofing material, and brake linings.


Asbestos is a set of six naturally occurring silicate minerals, which all have in common their asbestiform habit: i.e., long (roughly 1:20 aspect ratio), thin fibrous crystals, with each visible fiber composed of millions of microscopic "fibrils" that can be released by abrasion and other processes.


Asbestos is a heat resistant mineral used in many products and industries, but exposure can cause mesothelioma. Learn about the types, where it can be found and more.
