We are looking forward to import micro silica 97% from worldwide suppliers or exporters. Quantity Required : 10,000 Tons Shipping Terms : FOB Kazakhstan Payment Terms : 50 % T/T on order and 50 % T/T against shipping documents Microsilica (silica fume) is a by product from silicon metal or ferro silicon industries,is an amorphous silicon dioxide sio2 which is generated as a gas in submerged electrical arc furnaces during the reduction of very pure quartz. As the molten metal is produced, a silica-based gas is emitted. This gaseous fume, as it rises, cools rapidly and forms extremely minute,amorphous, spherical particles. The microsilica is collected in a bag house, a system for filtering the hot air and gases vented from the furnace. This gas vapor is condensed in bag house collectors as very fine powder of spherical particles that average 0.1 to 0.3 microns in diameter with a surface area of 17 to 30 m2/g. Microsilica can be used in concrete and refractory materials. Microsilica ,when used in concrete, it can improve concretes properties such as compressive strength, bond strength and abrasion resistance, reduces permeability,and therefore helps in protecting reinforcing steel from corrosion. At the same time, microslica can still be used in the procustion of refractory and porcelain, to raise intensity and durability, it also can be used in paint, coating resin rubber and other high molecular as a filler material to improve the material overall performance.
Silicon powder is silicon that has been ground into a finely powdered dust. Depending on the purity of the silicon powder, it can be used for many purposes. It can be sintered, alloyed with metals to harden the mixture, made into microchips, used as a reactant in silicon compounds, or used in glass plasma deposition. Powdered silicon usually is made without any additional elements, but it can be mixed with elements such as carbon or oxygen to create different powders.

Expanded clay is a lightweight porous building material obtained by firing clay or shale. Expanded clay gravel has an oval shape. Expanded clay rubble differs only in that its grains are mostly cubic in shape with sharp edges and corners. It is also produced in the form of sand - expanded clay sand. Depending on the mode of processing of clay or slate, it is possible to obtain expanded clay of various bulk density (volumetric weight) - from 350 to 600 kg/mâ³ and above. Used as a heater in the form of backfill, as well as for the production of lightweight concrete - expanded clay concrete. Expanded clay is also used in agriculture and hydroponics; it is used in domestic floriculture and as part of the soil in terrariums. Expanded clay, whose price is at a very affordable level, not only for construction organizations, but also for individuals, is in high demand. Due to its unique properties this building material is most in demand as: Economical insulation, used for walls, floors, ceilings, basements; Filler for lightweight concrete; Decorative material, allowing ensuring proper thermal insulation of soil and lawns; Drainage and thermal insulation material for earth embankments of roads, the laying of which is carried out in water-saturated soils.
Metallurgical slag (iron-containing flux). Content: - FE2O3 42-48%, - SIO2 10-12% - AL2O3 4,47% - CaO 20 - 25% - MgO 5,43% Used for production: - "Portland" cement, - Fertilizers, - Brake pads, - Metal blanks and articles, - Construction, - Construction of railway roads and rails Our slag can be used as an agglomerate in the production of blast furnace ore. Iron oxide prevails in the form of FeO - which allows you to additionally obtain iron from the flux during smelting.
