Quartz stone, quartz stone plate is produced by
the manufacturer to its plate of a short panel because of its major components
as high as 93% quartz content, it is called quartz.
Quartz is a physical and chemical properties are very stable mineral
resources to foreign imports perfect stone quartz stone quartz stone particles used as
raw material.
Mineral composition of silicon oxide SiO2. Mainly refers to widespread
trigonal system at low temperature quartz (α-quartz). When the temperature is
above 573 ℃, then become a hexagonal high-temperature quartz (β-quartz).
Low-temperature quartz crystal with a spire of the six-party columnar
Changcheng. There are stripes cylinder, there is the left and right-shaped
crystal-shaped crystal difference. Double-crystal is widespread, the most common
for Dauphin double-crystal and Brazil twins. Usually family was crystal or
granular, blocky aggregates. Pure person is a colorless and transparent, but
most contain a trace amount due to ions or finely dispersed pigment color
wrapped body, or because a color was the heart of a variety of colors, and to
reduce transparency. Glass, luster, fracture Changchengnongxing oil sheen. Mohs
hardness 7, the proportion of 2.65. Shell fracture. A strong piezoelectric and
optical activity.
Due to particle size, color, inclusions, etc. There are many different
variants: ① significant crystal are: colorless and transparent crystal; purple
amethyst (commonly known as Amethyst); smoke yellow, tobacco brown to near
black, yellow quartz, smoky quartz or smoky quartz; light yellow, transparent
yellow crystal; roses red rose quartz (commonly known as ROSE QUARTZ); milky
white milk quartz. Containing hematite or mica because of such scale-like
inclusions in the sand in spots shining stone. ② implicit qualitative kinds of
crystal are: microcrystalline composition of fibrous pulp stone (chalcedony);
colloid causes of agate; from asbestos fibrous quartz account made of tiger eye
stone. ③ qualitative kinds of hidden crystal formed by granular ceramics, often
mixed with other minerals of the material, opaque, mainly flint, gray to black
(commonly known as flint). Jasper, because iron-containing impurities which
Chenganhongse or green-yellow, green and other colors. A large quartz crystals
mainly in pegmatite crystal cave; bulk of ordinary produced in hydrothermal
veins; granular quartz are granite, gneiss and sandstone and many other major
mineral composition of rocks. In addition to crystal, agate and other precious
stones or process used materials, a more general pure quartz glass for a large
number of raw materials, abrasive materials, refractory materials such as
silicon. Impure quartz is an important building materials.
