Glass is known to get out of the sand, but the sand is not suitable for everyone. Raw materials required for optical glass, must be different special qualities. First and foremost it needs to be clean. Quartz sand is pure silicon dioxide SiO2, with virtually no impurities. Namely this property allows you to brew from the glass for optical instruments – telescopes, microscopes, and even regular glasses.
Quartz sand boiled and artificial jewelry crystal. It is suitable for the manufacture of rhinestones.
Quartz sand is also used for the manufacture of coloured glass enamels. Such enamels used in the painting of decorative items made of metal and porcelain. Enamel of quartz sand has the desired opacity and hue she can give any. This is done by adding salts of various metals.
Glass enamel is applied to the product before firing.
The basis of modern electronics – pure silicon. It is also produced from quartz sand. Silicon is produced by electrolysis of a melt of quartz sand.
Since quartz sand is a hard material, it is often used in the form of various abrasives. Abrasive grinding or cutting material. Quartz sand make emery wheels, emery wheels and emery paper. The manufacture of such products was possible because the quartz sand has a high hardness. Quartz sand used in sandblasters, which cleans a variety of surfaces.
Quartz sand is an insulator and a good heat accumulator. So it is used as filler for electric heaters with electric coils. They fill the space between the turns of the heating electric spiral and the wall of the fuel element.
Recently liquid glass has gained much popularity. This material, which is used in the production of construction and repair work to strengthen the foundations, as well as some cladding and decorative design decisions. Liquid glass is a sodium salt of silicic acid Na2SiO3. Many know this composition is a silicate glue. For gluing paper, he now almost never used, but in construction its value is not lost, since it is quite resistant to various influences, both the atmospheric and mechanical.
