silicon /sil·i·con/ (sil´ĭ-kon) a chemical element, at. no. 14, symbol Si. silicon carbide a compound of silicon and carbon used in dentistry as an abrasive agent. silicon dioxide silica.
silicon (Si) [sil′ikon] Etymology: L, silex, flint a nonmetallic element, second to oxygen as the most abundant of the elements in earth's crust. Its atomic number is 14, and its atomic mass is 28.09. It occurs in nature as silicon dioxide and in silicates. The silicates are used as detergents, corrosion inhibitors, adhesives, and sealants. Elemental silicon is used in metallurgy and in transistors and other electronic components. About 60% of the rocks in the earth's crust contain silicon, and silica dusts are associated with many mining operations. Protracted inhalation of silica dusts can cause silicosis, which increases the susceptibility to other pulmonary diseases. silicon, n a mineral/element (Si) that has been used for osteoporosis to increase the integrity and strength of the connective tissue matrix of bone. silicon (Si) (sil´ikon), n a nonmetallic element, second to oxygen as the most abundant of the elements. Its atomic number is 14, and its atomic weight is 28. It occurs in nature as silicon dioxide and in silicates. The silicates are used as detergents, corrosion inhibitors, adhesives, and sealants. Elemental silicon is used in metallurgy and in transistors and other electronic components. Protracted inhalation of silica dusts may cause silicosis, which increases susceptibility to other pulmonary diseases. silicon a chemical element, atomic number 14, atomic weight 28.086, symbol Si. See Table 6. See also silica. silicon A nonmetallic element–atomic number 14, atomic weight 28.086 present in nature as silica and silicates; silicon is integral to semiconductors and solar batteries, and essential for normal growth and skeletal development in rats
and chickens; a silicon deficiency state is not known in man Patient discussion about Silicon compounds. Q. Do any of you with FM have silicone breast implants, or have you ever had them? How about saline? My silicone implants expired on the surgeon's shelf before they went in my body. Both implants ruptured and disintegrated within 5 years of implantation. I was diagnosed with FM shortly after 2 surgeries to remove silicone goo. Just wondering if anyone else has made the connection. Thank you! A. As far as I know several studies failed to prove there is a connection between rupture of breast implants and fibromyalgia, as did the FDA conclude. Indeed I heard about one study that found this connection, but it seemed like a very problematic one.
