Silica Powder
Silica powder- Quartz powder: We are also manufacturing Silica powder. This is natural silica having purity of more than 99.7% SiO2. This silica powder comes in a very snow white color, the whiteness in A grade silica is more than 96%. Silica powder is available in 100 mesh, 200 mesh, 300 mesh, 10 microns D-97. The average particle size in Micronised Silica powder in below 5 microns. The Chemical composition of our silica powder is as under:-
- Quartz Silica powder: We have Quartz Silica powder with Maximum Purity Of 99.75% SiO2. The Mesh Size is available from 100 mesh to 300 Mesh. The Brightness in 1st grade quartz powder is 97%. The Minimum Sio2 % in our Mining area is 98.5% it means we have 98.5% purity in our lower grade which it best available in India. Quartz silica powder is suitable for all Ceramic applications, Ceramic Colours, Creamic Frits, Paint Industries and other applications.
- Quartz Silica Sand: In addition to above We also Manufacturer Quartz Silica Sand of Same purity 99.75% in 1st Grade and 98.5% in last grade. This sand is super white in color and available in 0.1 mm to 3.0 mm also in mesh size like 8/12, 16/30, 24/60, 30/80, 50/150 etc. Other than above regular sizes Mesh sizes are also available as per customers requirement in case of Bulk Orders Minimum 100 M.T.
- Micro Silica powder: We are also Manufacturing Micro Silica powder With Average particle size 3 to 4 Microns and Topcut 10 to 12 Microns which is Above 1000 Mesh.

Snow White Quartz Silica Powder
Quartz is the most abundant and most common mineral on the Earth. It is found in almost every geological environment and also it is at least a component of almost every rock type. It has a hexagonal crystal structure and is made of trigonal crystallized silica. It is most varied in terms of varieties, colors and forms.
The most important distinction between the types of quartz is that one is of macrocrystalline, which is individual crystal visible to the unaided eye, and the other is microcrystalline or cryptodrystalline varieties, aggregates of crysstals visible only under high magnification. Chalcedony is the generic term for cryptocrystalline quartz. The transparent variety tends to be macrocrystalline and the cryptocrystalline varieties are either translucent or mostly opaque.
The name "quartz" has been derived from the German "Quarz," a Slavic origin. It is the most common material identified as mystical substance maban in the Australian Aboriginal mythology. Pliny the Elder, a Roman naturalist believed quartz to be a permanently frozen ice. According to him, quartz is found near glaciers in the Alps and that the crystals of quartz were fashioned into spheres to cool the hands. It was also known to him the ability of quartz to split light into a spectrum.
Nicolas Steno's study of quartz made way for the modern crystallography. His discovery states that no matter how distorted a quartz crystal is, the long prism faces always made a perfect 60 degree angle.
