Silica sand is obtained by crushing quartz.
The result is a granular material, very similar to a regular sand, but uniform in chemical composition and particle size.
Silica sand is used in many industries.
Glass, as is known, is prepared from the sand, but the sandnot everyone is suitable. The raw materials required for the optical glass must be different special qualities. First of all it must be pure. Silica sand is pure SiO2 silicon dioxide with virtually no impurities. It is this property and allows you to cook from his glass for optical instruments - telescopes, microscopes, and even the common points.
From quartz sand boil and artificial jewelery crystal. Suitable for making it and rhinestones.
Quartz sand is also used tomanufacture of colored glass enamels. These enamels are used in the painting of decorative items made of metal and porcelain. Enamel is made of quartz sand has the necessary degree of transparency, and the shade it can be given any. This is done by adding the different metal salts.
Glass enamel is applied to the product before baking.
The basis of modern electronics - pure silicon. It is also prepared from quartz. Produce silicon by electrolysis of a melt of quartz sand.
Because silica sand is solidmaterial, it is often used in the form of various abrasives. Abrasive - abrasive or cutting material. From quartz sand make emery wheels, emery wheels and sandpaper. Production of such products has been made possible because the quartz sand has a high hardness. Silica sand used in sandblasting which cleans a variety of surfaces.
Silica sand is an insulator and a goodheat storage. Therefore, its use as a filler for electric devices with electric coils. They fill the space between the turns of electric heating spirals and the wall of the fuel element.
More recently gained greater waterglasspopularity. This material, which is used in the production of construction and repair works to strengthen the foundations, as well as some of facing and decorative design decisions. Sodium silicate is a sodium salt of silicic acid Na2SiO3. Many familiar with this part - a silicate glue. For gluing paper he is now almost never used, but in the construction of its value is not lost, as is quite resistant to various influences, both atmospheric and mechanical.
