Fused silica is a glass consisting of pure silica (SiO2) in amorphous form. Fused quartz has high working and melting temperatures, making it less desirable for most common applications. Fused silica is a glass consisting of pure silica in amorphous form. Applications â?? Electrode flux coating Optical components

Calcined Bauxite: Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application. We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices. Applications of Calcined Bauxite: Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%. Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.

Dolomite: Dolomite a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick. They are found all over the world and are quite common in sedimentary rock sequences. These rocks are called appropriately enough dolomitic limestone. Applications: - Dolomite is chosen for many construction and building product applications due to its increased hardness and density. - Asphalt and concrete applications prefer dolomite as filler for its higher strength and hardness. - Dolomite also finds use in a number of applications as a source of magnesium such as glass and ceramics manufacture, as well as a sintering agent in iron ore - Palletization and as a flux agent in steel making. - Farmers use dolomite for agricultural pH control. - The chemical industry uses the mineral dolomite in making magnesium salts including magnesia, magnesium oxide (MgO), which is used in pharmaceuticals.

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.

Fly Ash: Fly Ash is by product generated during combustion of coal, and comprises the fine particles that rise with the flue gases. Ash which is collected from the bottom is termed bottom ash. Fly ash is collected by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the type of coal being used, the specification of Fly Ash varies considerably, but Fly Ash contains substantial amounts of silicon dioxide and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata. We are a reputed Fly Ash Exporter based in India and are supplying Fly Ash different cement, ready mix concrete, steel, refractories and construction industries. The Major Utilization Areas Of Fly Ash : - Manufacture of Portland Pozzolanic Cement & Performance improver in Ordinary Portland cement (OPC). - Part replacement of OPC in cement concrete. - High volume Fly Ash concrete. - Roller Compacted Concrete used for dam & pavement construction. - Manufacture of ash bricks and other building products. - Construction of road embankments, structural fills, low lying area development. - As a soil amender in agriculture and wasteland development. Types of Fly Ash: - According to the type of coal used fly is classified into two types. Anthracite and bituminous coal produces Fly Ash classified as class F. Class C Fly Ash is produced by burning lignite or sub-bituminous coal. Class C Fly Ash has self-cementing properties. - Class F and Class C Fly Ash are products of the combustion of coal in large power plants. Fly Ash is collected in electrostatic precipitators or baghouses, and then transferred to large silos for shipment. When needed, Fly Ash is classified by precise particle size requirements, thus assuring a uniform, quality product. - Class F Fly Ash is available in the largest quantities. Class F is generally low in lime, usually under 15 percent, and contains a greater combination of silica, alumina and iron (greater than 70 percent) than Class C Fly Ash. - Class C Fly Ash normally comes from coals which may produce an ash with higher lime content generally more than 15 percent often as high as 30 percent. Elevated CaO may give Class C unique self-hardening characteristics. Minimum Order Quantity : 1 container
