Fused quartz from 200nm to 2.2um has high transmittance and low thermal expansion coefficient, which makes it an ideal choice for spherical lens in ultraviolet ray, visible light and near infrared spectrum applications with strict requirements. Spherical lens is commonly used to improve signal coupling between optical fibers, transmitters and detectors, as well as objective lenses in endoscopy and bar code scanning applications. Hemispherical lens simplify the integration of the whole system.

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.
