Asbestos can have several definitions, commercial, mineralogical and epidemiological : 1. Mineralogically, asbestos includes certain silicate minerals that have a highly fibrous (asbestiform) structure, are heat resistant and chemically inert, possess high electrical insulating qualities, and are of sufficient flexibility to be woven. 2. Commercially asbestos was a term used for three industrial materials: Chrysotile, amosite and crocidolite. 3. Epidemiologically, asbestos includes any serpentine or amphibole minerals that can generate respirable carcinogene fibre in dusts (mindat.org). Johannes Schmidt (talk) 18:10, 22 November 2021 (UTC)
