Chrysotile Mg3Si2H4O9 - PubChe

Chrysotile, the most abundant form of asbestos in industrial applications, occurs naturally in fiber bundle lengths ranging from several millimeters to over 10 cm. Chrysotile was the predominant fiber type in use in buildings. Other uses include paper products, paint and caulking, textiles and plastics Asbestos, Crocidolite Asbestos, Crocidolite (Fe2Mg3Na2 (SiO3)8) Asbestos, Crocidolite (Fe5Na2 (SiO3)8 Its idealized chemical formula is Mg3 (Si2O5) (OH)4. Amosite, (brown in color),CAS No. 12172-73-5, is a trade name for the amphiboles belonging to the cummingtonite-grunerite solid solution series, commonly from Africa, named as an acronym from Asbestos Mines of South Africa. One formula given for amosite is Fe7Si8O22 (OH)2 ASBESTOS 135 4. CHEMICAL AND PHYSICAL INFORMATION 4.1 CHEMICAL IDENTITY Asbestos is a generic term for a group of six naturally-occurring, fibrous silicate minerals that have been widely used in commercial products. Asbestos minerals fall into two groups or classes, serpentine asbestos and amphibole asbestos Asbestos, any of several minerals that readily separate into long, flexible fibres. Chrysotile, the fibrous form of the mineral serpentine, is the best-known type and accounts for about 95 percent of all asbestos in commercial use. It is a hydrous magnesium silicate with the chemical composition of Mg 3 Si 2 O 5 (OH) 4

Crocidolite Fe2H16Mg3Na2O24Si8+14 - PubChe

Formula: Mg3(Si2O5)(OH)4 Physical Characteristics : White asbestos, or chrysotile, is the only type of the six that belongs to the serpentine class. Fibers in chrysotile asbestos curl and wrap around each other, which differentiates it from the other types of asbestos belonging to the amphibole family and make it more flexible silicate having the chemical formula 1.5Mg0 5.5Fe0 8SiO2 H20. The seams break down readily to yield long, somewhat harsh fibers, brownish-yellow to almost white in color depending upon the quality. Amosite is used largely for making asbestos cement and heat-insulating products and is mined only in the Union of South Africa. It has good. Asbestos is a commercial term that includes six regulated asbestiform silicate (silicon + oxygen) minerals. Because this group of silicate minerals can be readily separated into thin, strong fibers that are flexible, heat resistant, and chemically inert, asbestos minerals were once used in a wide variety of products

The chemical feature common to all asbestos is that they are hydrated silicates The degree of hydration varies from approximately one per cent in some types to as much as approximately 14 per cent in most kinds of chiysotile It generally accepted that asbestos is a metamorphic product derived from certain types of silica-bearing minerals Interestingly enough, most asbestos minerals have non-asbestos counterparts with identical chemical compositions. In the case of tremolite, anthophyllite and actinolite, the word asbestos is added after the mineral name to distinguish it from the non-asbestos form It is a soft, fibrous silicate mineral in the serpentine subgroup of phyllosilicates; as such, it is distinct from other asbestiform minerals in the amphibole group. Its idealized chemical formula is Mg 3 (Si 2 O 5) (OH) 4 Asbestos. Fibrous incombustible mineral composed of magnesium and calcium silicates with or without other elements. It is relatively inert chemically and used in thermal insulation and fireproofing. Inhalation of dust causes asbestosis and later lung and gastrointestinal neoplasms

Asbestos is a slender, fine, flaxy fiber. Long term occupational exposure to the dust can result in lung cancer. Asbestos is resistant to fire and most solvents. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment formula (Mg 6 O 4 (OH) 8)-4 is intercalated between each silicate tetrahedra sheet. Asbestos fibers used in most industrial applications consist of aggregates of smaller units (fibrils). This is most evident with chrysotile that exhibits an inherent, well-defined unit fiber The chemical formula for asbestos is Mg3Si2O5(OH)4. As you can see there is no carbon in the formula, therefore it is inorganic
