Asbestos Properties

Asbestos is a fibrous mineral composed of silicate. Typically, asbestos naturally occurs in metamorphic and igneous rocks. Asbestos is used in insulation, adhesives, textiles, cement piping, cement siding and many other materials. Asbestos can dangerous when it begins to break down, releasing of fibers into the air people inhale.

  1. Classification

    • Amphibole asbestos is used in the construction of cement pipes.

      According to the Agency for Toxic Substances & Disease Registry, asbestos is either classified as amphibole or chrysotile. Amphibole asbestos contains fibers that are hard and stiff. This form of asbestos is used in materials such as cement piping. Chrysotile asbestos contain fibers that are softer and flexible. Chrysotile asbestos is more commonly used in textiles and insulation.

    Physical Properties

    • Asbestos is used in so many materials because it is heat resistant, as well as being resistant to some forms of chemicals such as acid. Asbestos also has high tensile strength. This means materials that contain asbestos would require large amounts of pressure to make the material bend or curve. According to Minerals Zone, asbestos has a "tensile strength surpassing that of steel."

    Chemical Properties

    • Asbestos varies in color.

      Asbestos is considered a solid that has no odor and taste. Depending on the composition of asbestos, the color varies. Asbestos containing iron and magnesium may show a pale tinge of green. If asbestos doesn't contain any iron, it will be a pale white. Asbestos containing iron and sodium will range from a bluish green to lavender.

    Types

    • Asbestos is used in insulation.

      There are various types of asbestos. Examples include vermiculite and crocidolite. Vermiculite is a type of asbestos used in insulation and soil amendment (to extend the quality of the soil). Crocidolite was once used in rope and yarn, but is now used in insulation.

    Hazards

    • Power plants can be a source of asbestos contamination.

      Long-term exposure to asbestos can lead to the development of diseases including mesothelioma, respiratory failure and lung cancer. Contact with asbestos usually occurs through occupational exposure. Such jobs and workplaces include automotive repair, construction, power plants, steel mills and railroads.
