Asbestos (1332-21-4) is the generic term used to describe over 30 different types of naturally occurring hydrated silicates representing two mineral groups (serpentine and amphiboles) that separate into fibres on mechanical processing. While the exact taxonomy continues to evolve, the sole serpentine variety is called chrysotile (12001-29-5) while the amphiboles include five forms  

White asbestos (12001-29-5) refers to the degree to which the mineral surface achieves complete reflectance over the visible spectrum rather than to the actual colour or hue of the mineral consequently, white describes multiple asbestos types, although it is most commonly applied to actinolite, chrysotile, and sometimes anthophyllite and tremolite. Similarly, while brown asbestos principally refers to amosite, it actually describes the degree to which the mineral deviates from colourlessness toward yellow, tan, or brown. 

Asbestos is resistant to heat, moisture, chemicals, microorganisms, wear, deformation, and decay and insulates against noise, heat, and electricity. It has been widely used commercially in fabrics, paper, filters, fillers, insulating boards, cements, fireproof garments, curtains, shields, brake linings, shingles, pipe coverings, and moulded products. 

Unfortunately, inhalation of asbestos fibres can lead to asbestosis, bronchogenic cancer, and mesothelioma. Other diseases and cancers have been reported, including those of the gastrointestinal tract. Less risk of exposure is presented by those products in which asbestos is embedded in a cement, plastic, asphalt, resin, mineral, or other binder in such a way that the fibres are only released and become airborne if the product is cut, abraded, damaged, or otherwise worked.

SYNONYMS Chrysotile, amosite, crocidolite, tremolite, anthophyllite, actinolite, tremolite, actinolite, serpentine chrysotile, white asbestos, blue asbestos. 

Asbestos. Asbestos is a generic name for naturally occurring mineral silicate fibres of the Serpentine and Amphibole series. In the Serpentine series is Chrysotile, commonly kno m as white asbestos. In the amphibole series are Actinolite, Amosite or Mysorite (commonly known as brown asbestos), Anthophyllite, Crocidolite (commonly known as blue asbestos) and Tremolite. All types of asbestos can be hazardous to health, blue and brown asbestos being the more dangerous types. ICAO A2... 

Double-chain silicates, shown in Figure I5.13f, find some SiO units sharing two oxygens while others share three. The repeating unit is Si40if. Five double-chain silicates [tremolite, anthophyllite, actinolite, amosite ( brown asbestos ), crocidolite ( blue asbestos ), all members of the amphibole family of minerals] and the serpentine mineral chrysotile ( white asbestos ) are classified under the generic name asbestos. The molecular-level chain structure of these materials is reflected in... 

Asbestos is the term for the fibrous form of a number of naturally occurring crystalline silicate minerals, which have been exploited commercially and are still mined and processed in various countries such as South Africa, Canada, the Former Soviet Union and China. The three main types of asbestos that have been commercially produced are Chrysotile, Amosite and Crocidolite, which are commonly referred to as White, Brown and Blue asbestos respectively. Other rarer forms of asbestos include Tremolite, Anthophyllite and Actinolite, which may be found either individually or as contamination within the three main types. 

Asbestos, blue, brown or white, includes each of the following hydrated mineral silicates chrysotile, crocidolite, amosite, anthophyllite asbestos, tremolite asbestos, actinolite asbestos, and every product containing any of these materials. US 173.216...
