Quartz sand is received when crushing quartz. As a result the bulk very similar to standard sand turns out, but uniform in the chemical composition and particle size. Quartz sand is applied in many industries.
Optical glass
Glass is received, as we know, from sand, but sand approaches not everyone. The raw materials necessary for optical glass have to differ in special qualities. First of all it has to be clean. Quartz sand represents pure SiO2 silicon dioxide, practically without impurity. This property also allows to cook from it glass for optical tools – telescopes, microscopes and even normal points.
From quartz sand cook also artificial jewelry crystal. It is suitable and for production of rhinestones.
Colored enamels
Quartz sand is applied also to production of colored glass enamels. Such enamels are used in painting of decorative metal wares and porcelain. Enamel from quartz sand possesses the necessary degree of transparency, and shade it can give any. It becomes by means of addition of salts of various metals.
Glass enamel is applied on product before roasting.
Pure silicon
Fundamentals of modern radio electronics – pure silicon. It is also received from quartz sand. Produce silicon by electrolysis of fusion from quartz sand.
Abrasive properties
As quartz sand is solid material, it is often applied in the form of various abrasives. Abrasive – the grinding or cutting material. From quartz sand take emery wheels, emery disks and abrasive paper. Production of similar products has become possible as quartz sand has the increased hardness. Quartz sand is applied also in peskostruyka with whom clean various surfaces.
Heating coils
Quartz sand is dielectric and the good store of heat. Therefore it is used as filler for electric heaters with electric spiral. Fill with it space between rounds of heating electric spiral and wall of the fuel element.
Liquid glass
Recently liquid glass has won great popularity. It is material which is applied by production of construction and repair work to strengthening of the bases and also in some facing and decorative and design decisions. Liquid glass represents sodium salt of silicon Na2SiO3 acid. This structure is familiar to much - it is water glass cement. It now is practically not applied to paper pasting, but in construction of the value has not lost as it is quite resistant to various influences, both atmospheric, and mechanical.
