What is Beryllium? - Facts, Uses & Side Effects Beryllium is a chemical element known to have an atomic number of 4 and atomic symbol of Be. Used in ancient civilizations, beryllium as an element was discovered during the 1700s and 1800s. Contributing scientists include Rene-Just Hauy, Louis Nicolas Vauquelin, Antoine Bussy, and Friedrich Wohler.he primary source of element beryllium comes from the beryl mineral. The molecular weight of beryllium is 9.0g/mol. With regards to its physical properties, the color of beryllium is steel gray. Known to be a brittle metal, it is relatively soft.

The Mineral emerald The Mineral emerald. Emerald is the green variety of Beryl, and its most precious and valuable variety. Its intense green color has given it status as an important gemstone throughout the centuries. The color of Emerald is green to emerald-green. The light green form of Beryl is not recognized as Emerald, but rather Green Beryl. The deep color of Emerald is caused by traces of the element chromium, but sometimes also vanadium.

- Definition of Acrylic Acrylic is defined as a manufactured fiber in which the fiber forming substance is any long-chain synthetic polymer composed of at least 85% by weight of acrylonitrile units. Acrylic fibers create a fine, soft and luxurious fabric with the bulk and hand of wool.his fiber accounted for 5 percent of the fiber produced in the United States in 1990 with only three companies producing it at the time. Acrylic is used in apparel including sweaters, fleece fabrics, and socks and in home furnishings such as furniture, carpet, blankets, and upholstery fabrics.

Painting and Coatings Terms and Definitions Acrylic: A synthetic polymer used in high-performance latex or water-based paints. As the paint's binder, acrylic resins enable the coating to last longer and retain its color. Acrylic Latex Paint: Water-thinned paint which employs acrylic resin as the majority of the binder. Other binders which may be added to reduce cost or add specific properties include styrene, epoxy, and poly-vinyl acetate.

- Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.he most important are beryl (beryllium aluminium silicate) and bertrandite (beryllium silicate). Emerald and aquamarine are precious forms of beryl. The metal is usually prepared by reducing beryllium fluoride with magnesium metal.
