    TEXT VERSION OF SLIDE:

    Title: Silicates
    Type: Text Slide
    Content: SiO4

    Speaker Notes: A different class of minerals which contain the same amount of silicon are the silicates. Silicates have a basic ratio of atoms of silicon to atoms of oxygen that corresponds to a chemical formula of SiO4. Silicates also can contain other elements such as aluminum, magnesium, or lead. Examples of silicates are mica, soapstone, talc, portland cement, fiberglass, mineral wools, refractive ceramic fibers, and asbestos. This slide program will not deal with silicates.
