Gayatri Minerals

We are supplier and exporter of Silica Sand. Silica Sand * Silica Sand is a type of sand usually available in the form of quartz. It is a hard and crystalline form of mineral components. * Silica sand is the most abundant mineral with the purity more than 99.0%. It is the preferred choice of consumption for various industrial purposes.

Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.

Silica sand,� also known as quartz sand, white sand, or industrial sand,� is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz â?? a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on� Mohs hardness scale, making it ideal for use as� filtration media� and� abrasive blasting sands. Although quartz is often white or colourless, it can come in a wide range of shades. The colour of each sand deposit depends largely on the variety of minerals and rock detritus that make up the resource. In order to be considered a silica sand the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criteria, it will qualify as whatâ??s often called â??regularâ?? sand. Regular sand,� also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for� concrete applications� can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.

Ball Clay: A member of kaolinite family, Ball Clay is renowned for its plasticity and green strength. They consists varying proportions of kaolinite, mica and quartz, with small amounts of organic matter and other minerals, and are commercially values because they increase the workability and strength of various ceramic bodies and have white or near white firing characteristics. Ball clay is processed to minimize the levels of coarse particles. This enhances better workability and higher strength. Applications : It forms a major part of many ceramic applications, including sanitary ware, tiles, table wares and to an increasing extent non-ceramic applications like functional fillers and advanced application for example technical ceramics.

Specifications Product : Quartz Silica Use : Industrial Use Color : White to Super Snow White Form : Powder & Grains Packaging Type : Small Plastic Bags / Jumbo Bags Packaging size : 50kgs / 1000-1200 kgs Whiteness : 90 to 95% Quartz is made up of a lattice of silica (SiO2) tetrahedral. It is the 2nd most common mineral in the world. Its very hard rock having hardness around 7 on the Mohs scale and its density is 2.65 g/cm3. Quartz is a common constituent of granite, sand stone, lime stone and many igneous, sedimentary and metamorphic rocks. It occurs in hydrothermal veins and pegmatites. Well-formed crystals may reach several meters in length and weigh hundreds of kilograms. The variety of quartz occurs either in translucent or mostly opaque, while the transparent varieties tend to be macrocrystalline. Although many of the varietal names historically arose from the colour of the mineral, current scientific naming schemes refer primarily to the micro structure of the mineral. Colour is a secondary identifier for the cryptocrystalline minerals, although it is a primary identifier for the macrocrystalline varieties. This does not always hold true. Not all varieties of quartz are naturally occurring. Some coloured mineral is produced by heat treatment. At PEEKAY MINERALS only natural Quartz is available. The quartz mineral is usually processed in the grain size of 0 to 6 mm. However, it can further be ground in fine mesh as per buyers' application choice or demand. For commercial classification the qualities of Quartz are governed as identification marks like Glassy, Snow white, White or Semi-white grades. The processing techniques at PEEKAY MINERALS ensures consistent quality, control of size and freedom from impurities at pocket friendly costs. Application: Manufacture in glass Paints and coatings Abrasives Refractories Electronic components As silica in many more applications Features: Free from impurities Controlled size of grains High purity
