説明

Silicon dioxide, generally known as silica, is a colorless solid that exists in numerous crystalline forms, the most common of which is quartz. Oxygen and silicon are the two most common elements in the earth’s crust, and silicon dioxide is the principal component of sand. Silica is used biologically, most notably by phytoplanktonic diatoms and the zooplankton radiolarians in their shells. The words silica and silicon come from the Latin silex meaning hard stone or fl int. Silica, SiO2, should not be confused with silicates or silicones. Silicates contain the basic tetrahedral unit SiO4 4- bonded to metal ions such as aluminum, iron, sodium, magnesium, calcium, and potassium to form numerous silicate minerals. Silicones are synthetic polymers made of monomers with at least two silicon atoms combined with an organic group and generally containing oxygen.

化学的特性

granular abrasive solid of varied colour, depending upon other

化学的特性

Silicon dioxide/crystalline silica is a component of many mineral dusts and materials which melts to a glass at very high temperature.

天然物の起源

QUARTZ is the mineral quartz, oxide of the nonmetallic element silicon, is the commonest of minerals, and appears in a greater number of forms than any other. Its formula is SiO2. Quartz commonly occurs in prismatic hexagonal crystals terminated by a pyramid. This pyramid is due to the equal development of two rhombohedrons, and may be observed in cases where one rhombohedron predominates. Cleavage is not observed; the fracture is typically conchoidal; hardness is 7; specific gravity, 2.65; luster, vitreous to greasy or dull; colorless to white, pink, purple, yellow, blue, green, smoky brown to nearly black; transparent to opaque.

特性

Silica can exist in either a crystalline or noncrystalline form. In quartz, SiO2 exists in the natural crystalline state and possesses long-range order, with the silicon atom covalently bonded to oxygen atoms in a tetrahedral arrangement in a regular repeating pattern. Glass is an example of noncrystalline silica. Although natural glasses exist, silica glasses are produced when silica is heated to an elevated temperature and then rapidly cooled. The rapid cooling does not allow the SiO2 to form a regular crystalline structure with long-range order. The result is a solid that behaves like a viscous liquid when heated. Glass is sometimes called a solid solution and fl ows at a very slow rate. This can sometimes be seen in old window glass where the bottom is slightly thicker than the top. The actual structures form a three-dimensional tetrahedral pattern. Silica is sold as sand and its main uses are for glass; ceramics; foundry sand, a source of silicon in the chemical industry; as a filtration media; a filler/extender; an abrasive; and as an adsorbent.

使用

As the art of glass making developed, individuals discovered how to produce different glasses by adding various substances to the silica melt. The addition of calcium strengthened the glass, and other substances imparted color to the glass. Iron and sulfur give brown glass, copper produces a light blue color, and cobalt a dark blue color. Manganese was added to produce a transparent glass, and antimony to clear the glass of bubbles. Most modern glass produced is soda-lime glass and consists of approximately 70% SiO2, 15% Na2O (soda), and 5% CaO (lime). Borosilicate glass is produced by adding about 13% B2O3. Borosilicate glass has a low coeffi cient of thermal expansion and is therefore very heat resistant. It is used extensively in laboratory glassware and in cooking where it is sold under the brand name Pyrex. Because of silica's high melting point, it is ideal for making molds for metal casting. It is regularly used to form iron, aluminum, and copper items. Silica is the primary filter medium used in wastewater treatment. Filtration systems often modify silica physically and chemically to produce activated silica formulations. Besides water treatment, activated silica gels used for chromatography in chemistry laboratories. In the construction industry, silica glass is used as fiber glass insulation, silica sand is a basic ingredient in cement and concrete, and is used indirectly in building products. Silica is used as filler in paints, adhesives, rubber, and coatings. It is added to personal care products such as tooth polishes.

使用

Formulators may select silicon dioxide (solum diaomeae) as an alternative to diatomaceous earth or clay, particularly when developing mineral make-up, pressed or loose powders. Silicon dioxide has abrasive, absorbent, and anti-caking properties, and can also reduce the transparency of a formulation. Silicon dioxide is the u.S. name for what is known as solum diatomeae.

使用

Silicon Dioxide is an anticaking agent, carrier, and dispersant that can absorb approximately 120% of its weight and remain free flowing. it is used in salt, flours, and powdered soups to prevent caking caused by moisture. it is also used in powdered coffee whitener, vanilla powder, baking powder, dried egg yolk, and tortilla chips. the usage level ranges from 1 to 2%. it is also termed silica, amorphous.

使用

Electronic components; piezoelectric control in filters, oscillators, frequency standards, wave filters, radio and TV components; barrel-finishing abra- sive.

定義

定義

A natural crystalline form of silica (SiO2).

定義

A purple form of the mineral quartz (silicon(IV) oxide, SiO2) used as a semiprecious gemstone. The color comes from impurities such as oxides of iron.

定義

agate: A variety of chalcedony thatforms in rock cavities and has a patternof concentrically arranged bandsor layers that lie parallel to the cavitywalls. These layers are frequently alternatingtones of brownish-red.
Moss agate does not show the samebanding and is a milky chalcedonycontaining mosslike or dendritic patternsformed by inclusions of manganeseand iron oxides. Agates areused in jewellery and for ornamentalpurposes.

定義

quartz: The most abundant andcommon mineral, consisting of crystallinesilica (silicon dioxide, SiO2),crystallizing in the trigonal system. Ithas a hardness of 7 on the Mohs’scale. Well-formed crystals of quartzare six-sided prisms terminating insix-sided pyramids. Quartz is ordinarilycolourless and transparent, inwhich form it is known as rock crystal.Coloured varieties, a number ofwhich are used as gemstones, includeamethyst, citrine quartz (yellow),rose quartz (pink), milk quartz(white), smoky quartz (grey-brown),chalcedony, agate, and jasper.Quartz occurs in many rocks, especiallyigneous rocks such as graniteand quartzite (of which it is the chiefconstituent), metamorphic rockssuch as gneisses and schists, and sedimentary rocks such as sandstone andlimestone. The mineral is piezoelectricand is used in oscillators. It isalso used in optical instruments andin glass, glaze, and abrasives.

危険性

Avoid inhalation of fine particles.

健康ハザード

Exposure to silica can result in the disease called silicosis. Silicosis is a disabling, nonreversible, and sometimes fatal lung disease caused by overexposure to respirable crystalline silica. In silicosis, silica particles enter the lung where they become trapped, producing areas of swelling. The swelling results in nodules that become progressively larger as the condition worsens. Silicosis is defi ned at several levels of severity: chronic silicosis, accelerated silicosis, and acute silicosis. Chronic silicosis results from long-term (20 years) exposure to low concentrations of silica, whereas acute silicosis is the result of a short-term exposure (a year or less) to high concentrations. Symptoms may not be obvious in cases of chronic silicosis and x-ray screening is recommended for at-risk groups. Th ese include sand-blasters, miners, laborers who regularly saw, drill, and jack-hammer concrete, and general construction such as tunnel drilling. In advanced stages of silicosis, individuals have difficulty breathing, especially when active.

安全性プロファイル

Confirmed carcinogen with experimental carcinogenic, tumorigenic, and neoplastigenic data. Experimental poison by intratracheal and intravenous routes. An inhalation hazard. Human systemic effects by inhalation: cough, dyspnea, liver effects. Incompatible with OF2, vinyl acetate. See also other silica entries

職業ばく露

Cristobalite is used in the manufacture of water glass, refractories, abrasives, ceramics and enamels. Quartz is used as a mineral, natural or synthetic fiber. Tridymite is used as a filtering and insulating media and as a refractory material for furnace linings. Workers are potentially exposed to crystalline silica in such industries as granite quarrying and cutting, foundry operations; metal, coal, dentistry, painting, and nonmetallic mining; and manufacture of clay and glass products.

Carcinogenicity

Silica was not mutagenic in bacterial assays; both positive and negative results have been reported in a wide variety of in vivo and in vitro genotoxic assays.

不和合性

Violent reactions with powerful oxidizers: fluorine, chlorine trifluoride; manganese trioxide; oxygen difluoride, hydrogen peroxide, etc.; acetylene; ammonia.
