Product Details. Paperback: pages ; Publisher: Oxford University Press, USA ( ) Language: English ; ISBN ; ISBN Asbestos is a generic name given to six needle-shaped minerals that have been used in commercial products. It is an industrial term rather than a mineralogical term, referring to specific fibrous mineral particles that possess high tensile strengths, large length-to-width ratios, flexibility and resistance to chemical and thermal degradation. Asbestos describes any mineral that is extremely fibrous and flexible. The term is very commonly used to describe the fibrous form of Chrysotile Serpentine, and may also be used in regards to the fibrous variety of Tremolite or Actinolite.

Asbestos is a generic name given to six fibrous minerals that have been used in commercial products. The six types of asbestos are chrysotile, crocidolite, amosite, anthophyllite asbestos, tremolite asbestos, and actinolite asbestos. Several properties that make asbestos so versatile and cost effective are high tensile strength, chemical and thermal stability, high.

The statement of task assigned to the committee for the study Review of the NIOSH Research Roadmap on Asbestos Fibers and Other Elongate Mineral Particles 1 asked five questions.

Asbestos has 2 sub-categories. They are Asbestos-Amphibole and Asbestos-Serpentine. They are categorized as such, due to the way in which they form. Serpentines form when certain igneous rocks come in contact with just-below-boiling water. A chemical reaction takes place creating a Serpentine rock.

Asbestos is a term applied to several mineral species when they occur in a fibrous form (asbestiform). When the mineral species are asbestiform, they have the physical characteristics associated with asbestos, such as large aspect ratio of fibers, flexibility, separability and weavability of fibers, and chemical and physical durability.
