تعريف silica. في الإنجليزية الإنجليزية القاموس.
- silici-
- Silicon dioxide
- Silica is silicon dioxide, a compound of silicon which is found in sand, quartz, and flint, and which is used to make glass. a chemical compound that exists naturally as sand, quartz, and flint, used in making glass (silex )
- any material with the composition SiO2 Often refers to a Jello-like sub-stance with that composition which can act as a rock cement or solidify by itself as chert, flint, or jasper
- a chemically stable and refractory glass made from silica alone
- Silicon dioxide, SiO&?
- Silicon dioxide (SiO2) Note 1: Silica may occur in crystalline or amorphous form, and occurs naturally in impure forms such as quartz and sand Note 2: Silica is the basic material of which the most common communication-grade optical fibers are presently made [After FAA]
- Silica can be found in water as a natural forming mineral or an additive to public water supplies Silica is not regulated by the EPA and does not cause any health concerns However, silica can cause spotting of glassware, fixtures, and automobiles during the cleaning process
- Silicon dioxide (Mineral consisting of or incorporating silica)
- is a form of silicon and is found as quartz and sand flint It is used in the production of glass, ceramics and abrasives Back to Organisms page | Back to Coral Reef page
- the fundamental silicon-oxygen compound, which has the empirical formula SiO2, and forms the basis of quartz and certain types of sand
- A pigment made from quartz sand that has been crushed or ground A reinforcing filler for paints; it imparts burnish resistance, sheen uniformity and good flatting
- a term for silicon carbide, usually quartz, a common mineral used in glass manufacture and in some instances glass decorating colors
- one of the earth's most abundant minerals and a vital ingredient in ceramic manufacture It is the basic component of glass as well as of ceramic glazes and high quality clayware bodies
- A combination of silicon and oxygen The mineral form is called quartz
- The common name for silicon dioxide A compound formed from silicon and oxygen Silica is a polymorph, that is, it exists in more than one state The states of silica are crystalline and noncrystalline (also called amorphous) Crystalline silica can take several forms: quartz (most common), cristobalite, tridymite, and four rare forms
- n silicon dioxide (SiO2); a main component in most igneous and metamorphic and many sedimentary rocks; often a cement or replacement for rocks and fossils; quartz
- any of the silica group of the silicate minerals
- It constitutes ordinary quartz (also opal and tridymite), and is artifically prepared as a very fine, white, tasteless, inodorous powder
- (SiO2) containing varying percentages of water
- Silicon dioxide This is a very common material, often forming the mineral quartz, but also forming flint, agate and much of the sand found on beaches and in sandstones Silicon and oxygen are both very common elements in the crust of the Earth, and therefore the proportion of silica present is used as a means of classifying igneous rocks into acid, intermediate and basic, the first being the richest in silica
- A hard, glassy mineral Quartz and opal are two forms of silica Since much sand is made of quartz, silica is very common in sand Some marine organisms use silica to build their shells
- Silicon dioxide (SiO2) occurring in crystalline, amorphous and impure forms (as in quartz, opal and sand) (Precipitated silica)
- {i} silicon dioxide, crystalline compound commonly found in sand and quartz (used to produce glass, cement, ceramic, and other products)
- The molecule formed of silicon and oxygen (SiO2) that is the basic building block of volcanic rocks and the most important factor controlling the fluidity of magma The higher a magma's silica content, the greater its viscosity or "stickiness "
- is a chemical compound comprised of silicon and two oxygen atoms (SiO2)
- Silicon dioxide, a mixture that is the main ingredient of glass The most common form of silica used in glassmaking has always been sand
- a white or colorless vitreous insoluble solid (SiO2); various forms occur widely in the earth's crust as quartz or cristobalite or tridymite or lechartelierite
- A hard, crystalline substance which is an essential ingredient in the manufacture of glass It occurs in nature in such mineral forms as sand, flint, quartz etc GANTAD
- Silica is an essential ingredient in the making of glass Most commonly derived from sand, pure silica is also used in the making of laboratory glass which is resistant to extremely high temperature
- Mineral that is composed of silicon dioxide, SiO2
