Sitall (stone): what is it, properties and application

Luxury jewelry with natural stones can not afford every lady. And I want to get something beautiful for everyone. To this end, scientists brought artificial stones from natural substances. With the help of nanotechnology, the crystal of the sitall was created. According to its external data, it is not inferior to many natural stones. To date, they are produced in different colors.

History of occurrence

Many people are interested in the sitall (stone). What is it? On the art phianites heard more, and the information about the Sitallas is not so widespread. The precious stone of the sitall is a glass-crystalline material. Abroad, the technology of its manufacture was developed earlier (in 1957). It belongs to the American Donald Stookey. The firm "Dow Corning", engaged in the production of these crystals, they were given the name "pyrocer".

In the Soviet Union, Isaak Kitaygorodsky was working on the development of sitaws. And many other Russian scientists have contributed to the development of crystal technology. So, sitall (stone) - what is this, where did this name come from? An unusual word was formed from two chemical elements that make up this crystal. From sicilium (silicon) took the syllable "si", from aluminum - the syllable "al", and it turned out sitall. It is very similar in composition to volcanic rock and refers to high-temperature silicate glass.

Characteristics and properties of a crystal

Fianit in its properties more like a diamond, but the sitall was copied under sapphires and emeralds. It is made of glass, but there are some distinctive features between them. The formula used to create this crystal, SiO ₂ , is very similar to rock crystal. It is the raw material for quartz glass. How does the sitall (stone) look like? Photos of this artificial crystal can be seen on the images in the article. He is quite firm and non-porous. How reliable is the stone of the Sitall? The properties of this crystal depend on how complex it is. And it consists of the smallest crystals, and therefore very dense, is equated with steel. By its hardness, it is surpassed only by a diamond. Stone well conducts heat, it is impossible to melt it at home. This was achieved thanks to lithium, aluminum and mineral raw materials, which are introduced into the composition.

Sitall beautifully poured, it is almost transparent, resistant to various chemical reactions. How can we connect so many crystals so that no pores form between them?

Manufacturing process

Glass has a natural property with time to crystallize. It was he who was the basis of the scientists in creating the sitall. The process of manufacturing this material resembles glass ceramics. For the beginning, prepare the raw materials - the charge. It may include several nucleators (constituents for clarification). For one millimeter of cubic, there are several billion of the smallest crystals.

Then such a charge necessarily melts. First, the center of the stone crystallizes, then the temperature is raised until new aggregates grow around it.

After that, the stone lends itself to cooling. That's how they get the sitall. Stone for jewelry purposes is used very widely. The technology of making the glass was used when pouring ruby glass for Kremlin stars in Moscow.

How to apply sitall

In what other spheres besides the manufacture of jewelry is this artificial stone used? The properties of the sitall can be adjusted by adding to it some elements, for example, perlite, dolomite, copper, silver. Therefore, the crystal is widely used in engineering. It is an excellent electrical insulator, fairly transparent, suitable for making lenses, mirrors, light filters.

Serves as an excellent material for coating metal parts. With such protection, the metal does not rust and has a beautiful appearance. Pipes with a silicon coating are used in the oil refining industry.

A stone with elements of aluminum and lithium is used in dentistry (for making seals).

Types of artificial crystal

The most common application was given to this artificial stone in the jewelry sphere. Sital has several species. A very popular ametrin, consisting of two colors and reminiscent of amethyst. No less popular is sultanite, capable of changing color.

Very many fashionistas are interested in sitall (stone). Many women are aware of this today. Silver and gold jewelry in our time can not be imagined without synthetic stones. Sitall "London" is a stone resembling a gray-blue topaz with a smoky shade. This nanocrystal is very well combined with alloys of gold and silver. If a girl has fair skin and light blue eyes, the Sitall London is ideal for her.

Also worth mentioning are the following types of sital: Citrine Madera, tourmaline, tanzanite, pink marquise, garnet trillion, etc.

Demand in the market of ornaments

We found out, sitall (stone) - what is it. Synthetic mineral is in no way inferior in its characteristics to sapphire, blue topaz, emerald. He has a very even color and good transparency. Still very important advantage is the sitall - it transfers high temperatures. This allows you to use it in decorations that are made by low tide. The crystals are placed in molds and the metal is poured into it, heated to 1000 degrees. Phianites of such a high temperature can not stand: either deformed or fade. But the sitallas are coping well with such a test, so the fianites have a serious competitor. Products with nanocrystal are very refined and relatively inexpensive.

The superiority of synthetic stones

Around synthetic stones there is much debate about their advantages and disadvantages. Jewelry artificial crystals are absolute analogues of natural minerals, but created in laboratory conditions. Real stones grow in the natural environment, and synthetic ones are grown artificially. They can be compared to flowers, which are courted in a greenhouse. There they are large, bright, blossom for a long time. So are the stones: in the laboratory you can experiment with color, composition, strength. Artificially grown crystals are in no way inferior to natural crystals, in some cases even superior to them. One of the most prominent representatives is sitall.

To synthetic developments of scientists also include Swarovski stones, sapphire crystal, cubic zirconia. They are used as analogues of various rare stones. Earrings, bracelets, rings with the use of these bright crystals greatly diversified the range of jewelry. Any woman will be pleased with the inserts from the sitall!
