Description and Uses

Fibrous glass is the name for a manufacturedfiber in which the fiber-forming substance is glass. Glassesare a class of materials made from silicon dioxide with oxides of various metals and other elements that solidify fromthe molten state without crystallization. Typically, glassfilaments .3 μm in diameter or glass “wool” with diameters down to 0.05 μm and length>1 μm. A fiber isconsidered to be a particle with a length-to-diameter ratioof 3:1 or greater. The volume of small diameter fiber production has not been determined. Fibers with diameters lessthan 1 μm are estimated to comprise less than 1% of thefibrous glass market. Specific gravity (H2O:1)=2.5.Hazard Identification (based on NFPA-704 M RatingSystem): Health 1, Flammability 0, Reactivity 0. Insolublein water.

Silica glass spheres are low density filler for coatings and plastics. Silica was used in synthesis of silicalite. Silica was also used to assist the catalytic growth of oxide and nitride nanowires.
