What are the main components of crystals and what are the components of crystals

Be. Silicon dioxide.

Crystals are highly pure silica and are monocrystalline.

Crystal is a colorless, transparent, large, quartz crystalline mineral. Its main chemical component is silica, which is a substance that "comes out of the same womb" as ordinary sand. When silica crystallizes perfectly, it is crystal; After silica gelatinization and dehydration, it is agate; The aqueous colloids of silica become opal when solidified; When the silica grains are less than a few microns, chalcedony, flint, and secondary quartzite are formed.

The chemical formula is SiO2. Pure, colorless, transparent crystal is a variant of quartz. The chemical composition contains Si—, O-.

It has a variety of colors due to the presence of different mixtures or mechanical mixtures. Purple and green are caused by iron (Fe2+) ions, violet can also be caused by titanium (Ti4+), and other colors are colored by color centers. In the crystal, it contains inclusions such as sandy and fragmented goethite, hematite, rutile, magnetite, garnet, chlorite and so on; Hair crystals contain inclusions of hair-like needle-like minerals that are visible to the naked eye.

Those containing manganese and iron are called amethyst; Iron (

Golden yellow or lemon color.

Called citrine; Those that contain manganese and titanium and are rose-colored are called rose quartz; The smoke-colored one is called smoky quartz; The brown one is called citrine; The black transparent one is called ink crystal; Those that are light green are called chalcedony.

Another temperament of crystal is that it is afraid of alkali and acid (except hydrofluoric acid), which is determined by the characteristics of silicon oxide.

Gemstones such as agate, when heated, rubbed, blown or blown, often emit a special smell reminiscent of garlic, horse meat, radish and pine, however, crystals have no odor in these cases.

Crystal is a quartz crystalline mineral whose main chemical components are:Silicon dioxide.

Crystal is a rare mineral, a type of gemstone, a quartz crystal, which belongs to the quartz family in mineralogy. The main chemical component is silica. When pure, colorless and transparent crystals are formed. When containing trace elements.

Al, Fe, etc. are pink, purple, yellow, brown, etc.

Irradiated trace elements form different types of color centers, producing different colors, such as purple, yellow, brown, pink, etc. Chi Shi with associated inclusions is called inclusion crystals, such as hair crystals and green ghosts.

Red rabbit fur, etc., the inner inclusions are rutile, tourmaline, actinolite, mica, chlorite, etc.

For a long time, crystal has been classified as a resistance to gemstones, and the hail of the guide code has caused the homogenization of crystal carvings in the market.

It is very serious, and seriously affects the artistic value and commercial value of crystal carvings. Therefore, the value of crystal carving products has a realistic significance.

The main component of crystal is silica, which is a crystalline body of minerals.

1. What is Crystal?

Crystal is a crystalline body of minerals, the main component of which is silicon dioxide. Due to its high transparency and beautiful appearance, it has a high value in jewelry, ornaments, handicrafts and other fields, and is also widely used in medicine, electronics, and other fields.

Second, the main component of crystal - silica preamble

1.SiO2, with the chemical formula SiO2 and molecular weight, is a colorless, transparent, brittle and hard mineral. It is widely found in nature and constitutes the structure of many quartz stones.

2.In the crystal, the content of silica reaches about 98%, which is also an important reason for the high transparency and strong luster of the crystal. In addition, crystals also contain trace elements, such as sodium, aluminum, lithium, potassium, etc., which can also affect the appearance and properties of crystals.

3. Types of crystals

There are many types of crystals, which can be divided into the following according to different classification criteria:

1.Quartz: Quartz is the most common type of crystal, and its composition is mainly silica. Quartz comes in a variety of colors and textures, and some varieties can also glow.

2.Red crystal: The color of red crystal is relatively bright, and it is mostly used in jewelry, jewelry and other fields.

3.Amethyst: Amethyst is often used in the production of ornaments, feng shui items, etc., which can bring a peaceful and positive aura.

4.Black crystal: Black crystal is often used to absorb negative energy and protect itself, and it is also a common material for some jewelry and ornaments.

Expand your knowledge:

1.Crystals are widely distributed in nature, mainly in volcanic areas, granite areas and other places around the world. Yunnan, Sichuan and other places in China also have a large number of crystal deposits.

2.Crystals have long held a mystical meaning in people's hearts, and are regarded as gemstones and mascots. In traditional Chinese culture, crystal is also regarded as one of the symbols of wisdom, clarity and noble qualities.

3.In addition to the wide range of applications in jewelry, ornaments, handicrafts and other fields, crystal has many other uses. For example, in the medical field, crystals are widely used to make medical devices such as scalpels and straws; In the field of electronics, crystal is one of the indispensable materials in the production of electronic components.

1. The main component of water or Qingjing is silica. Crystal, rare mineral, a kind of Baobdaite, quartz crystal, belongs to the quartz group in mineralogy, the main chemical component is silica, when pure, it forms a colorless and transparent crystal, when it contains trace elements AL, Fe, etc., it is purple, yellow, brown, etc., and forms different types of color centers by irradiating trace elements, producing different colors, such as purple, yellow, brown, pink, etc.

2. From a biogeochemical point of view, crystal, like other gemstones, is formed in a special geological structure environment, containing some trace elements that are beneficial to the human body, such as iron, copper, manganese, chin, zinc, nickel, diamond, selenium, etc., smoke quartz due to the formation of underground radioactive irradiation, and retain a small amount of radioactive elements (the content is very small, will not be harmful to the human body, but similar to radiation), these trace elements will be along the capillary sweat glands through regular friction with the human body, etc. It is immersed in the human body and promotes the balance of trace elements in the body, so that the body parts are more coordinated.

2. From the point of view of biogeochemistry, the crystal is the same as other gemstones, formed in a special geological structure environment, containing some trace elements beneficial to the human body, such as iron, copper, manganese, chin, zinc, nickel, diamond, selenium, etc., smoke quartz due to the formation of underground radioactive irradiation, and retain a small amount of radioactive elements (the content is very small, will not be harmful to the human body, but similar to radiation), these trace elements through the human body often rub and will be along the capillary sweat glands, etc., It is immersed in the human body to promote the balance of trace elements in the body, so that the body's parts are more coordinated.

The chemical composition of the crystal is silica and some trace metal elements.

When silica crystallizes perfectly, it is crystal; The crystallization is imperfect is quartz: silica is agate after gelatinization and dehydration; The aqueous colloids of silica become opal when solidified; When the silica grains are less than a few microns, they form chalcedony, flint, and secondary quartzite. The types and colors of crystals may be relatively abundant, because of the presence of these trace metal elements.

Trembling natural crystal is a relatively scarce mineral, the formation process is more complicated, its Mohs hardness is 7, and it is not easy to wear and tear.

The main chemical component of crystals is silicon dioxide. Crystal is a rare mineral, a type of gemstone, a quartz crystal, and belongs to the quartz family in mineralogy. When the crystal is pure, it forms colorless and transparent crystals, and when it contains trace elements such as aluminum and iron, it is pink, purple, yellow or brown.

Irradiated trace elements also form different types of color centers and produce different colors.

Crystal refers to colorless and transparent silica crystals, which belong to precious ores. It is included in the category of colored gemstone forest sail alongside ice chalcedony and tourmaline, and the output is small, and it is called "water jade" and "water essence" in ancient times. Burning.

The word crystal encompasses colorless and transparent glass, as well as natural crystal ores. Crystals are usually lumpy or granular aggregates, generally colorless, gray and milky white, and purple, red, smoky or brown when containing other mineral elements.

When silica crystals are perfect, it is crystal, and when it is imperfect, it is quartz. After silica gelatinization and dehydration, it is agate, and its aqueous colloidal body becomes opal after solidification. When the silica grains are smaller than a few microns, they form chalcedony, flint and secondary quartzite.
