Quartz (Silica SiO2) is the most common mineral in the Earths crust. Quartz is found in
sandstones, pegmatites granites, and other igneous rocks. It forms veins in the cracks of rocks.
There is a lot of heat and water where they form. Crystals are made when the quartz cools down.
The way the crystal looks depends on how hot it was when it was formed. It can be found in
layers or geodes, too. Geodes are hollow rocks that are lined with crystals. It has a hexagonal
crystal structure and is made of trigonal crystallized silica. It is most varied in terms of varieties,
colors and forms. Of all the minerals, quartz is closest to a pure chemical compound and has
constant physical properties.
It is hard, chemically inert and has a high melting point, attributable to the strength of the bonds
between the atoms and extremely resistant to weathering. These are prized qualities in
applications like foundries and filtration systems. Quartz may be transparent to translucent and
has a vitreous luster, hence it is used in glass and ceramics. Quartzs strength, silicon dioxide
contribution and non-reactive properties make it an indispensable ingredient in the production of
thousands of everyday products.
We supply Quartz in Lumps, grits/Sands and powder forms for various industrial
Quartz sand/grains in Glass Industry:-
Quartz is commonly known as silica sand for producing float glass, fiber glass, automotive glass,
clear container glass, Borosil glass and other types. We produce quartz powder for high purity
glass having extremely low levels of contaminating metal oxides, and other foreign particles with
the help of heavy magnetic separators used in mesh 25 to 32 or in mm size 0.1mm-0.3mm,
0.3mm - 1.2mm, 0.5mm-0.1mm, 1.2mm - 0.3mm.
Fused Quartz (Silica glass), vitreous silica glass: silica (SiO2) is used for very special
applications and has very low thermal expansion, is very hard and resists high temperatures
(1000 1500 C). It is also the most resistant against weathering (alkali ions leaching out of the
glass, while staining it). It is used for high temperature applications such as furnace tubes,
melting crucibles, Flat glass, Automotive Glass Hollow Glass (e.g. Thermal expansion, hardness,
