Keyway Industrial Limited Colloidal silica
What is Colloidal Silica/ Silica Sol?
Colloidal silica is a dispersion of amorphous silicon dioxide (silica) particles in water. These amorphous silica particles are produced by polymerizing silica nuclei from silicate solutions under alkaline conditions to form nanometer sized silica sols with high surface area. A charge is then induced on the silica nanoparticle surface that allows the silica particles to repel one another and form a stable dispersion, or colloid.
Colloidal Silica Characters:
Colloidal silicas are produced in a variety of grades that range in a number of factors. Particle size typically varies from 5nm to 40nm, and particle size distribution can vary from narrow to wide depending on the manufacturing process. Standard colloidal silica is stable at a pH from 8 - 10.5 and carries an anionic surface charge that is stabilized with sodium or ammonium. In certain grades, some of the silicon atoms in the silica particle are replaced with aluminate ions to allow for enhanced stability in a wider pH range, usually 3.5 - 10.5.
Colloidal Silica Application:
Densification of concrete, cement, and other materials.
Fine retention in paper manufacturing.
Enhanced bonding of waterborne adhesives.
Improved surface friction and anti-slip properties.
Wastewater filtration flocculant.
Investment casting binding.
Anti-soilant textile coatings.

As a general rule, The purer the sand, the clearer the products Silicon and oxygen are the earth's two most abundant elements and together they make silica, one of the earths three most common rock forming minerals. Akshar Minerals Silica sand is high purity natural crystalline silica. It is inherently bright, white, low in moisture and chemically inert in nature. Basically, It is made up of two main element Silica & Oxygen. Silica sand is made up of Silicon Dioxide. There are number of different uses of silica sand in the industrial and commercial sector, from golf courses to glass making . The chemical formula of Silica Sand is SiO2 Characteristics : High Purity Weather Resistant White Appearance Naturally Hard Controlled Particle size Chemically Inert Applications Akshar Minerals Silica sand is used depends on physical, chemical and mechanical characteristics such as grain size, shape color, structure and distribution as well as refractoriness strength and stability. There characteristics can differ depending on how mineral is processed after it is mined. This product gets easily mixed and can be used for high temperature applications like flat glass, furnace tubes and many more due to its excellent thermal expansion, hardness. It yields improved durability and burnish resistance. We make for all type of application in the industries like Glass industries, Sodium Silicate Industry, Golf course & Sport Ground, Adhesive and sealant, Rubber industry, Texture Wall Paint, Sand Blasting, Agro pesticide, Cosmetic industry, Soap & Detergent, Filtration Media, Power Plant & Petroleum, Construction Chemical Industry, Plastic, Fertilizer, Paint, Ceramic, Insulation, Foundry, Ramming Mass, Steel Industry, Landscaping, GRC & GRP Industry, Oil & Petroleum Industry, Oil Exploration & Oil Drilling.
Foundry Sand High Quality and high deposit foundry sand since thousands of years with Huge Reserve in Egypt which available in ZAFARAN AND ABOU ZNIEMA and yellow silica sand with quality greater than 98$while the WITH Quality of 99.10% Sio2 with and Iron content average from 0.018% -0.0.35% with practical size Distribution from 0.075 mm 0.85 mm,its High Quality with high whiteness and Low Al 2o3 support high casting products which used by Best Car factories. High Frequency Vibrating Screen supports us to produce different fines which meet multi casting uses. Because we are in Egypt land of a large various of minerals, in al sharqeya, we have Brown Silica sand with Purity of 96.5%-97% SIO 2. foundry sand where to find white silica sand? -White silica sand can be found in tow main places in Egypt -South Sinai where Abou zenima port main port which most Exported silica sand to India, UAE ,Turkey Zafrana quarries which far away from Cairo about 350 km What is purity of white silica sand?
