Ferro Silicon Ferro Silicon has a melting point of 1200�¯�¿�½?�?�°C to 1250�¯�¿�½?�?�°C with a boiling point of 2355�¯�¿�½?�?�°C and Ferro Silicon contains about 2% of calcium and alluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.
FerroChrome is a kind of Ferro alloy which is formed by Ferro and Chrome,it is an important alloy addition in steel making. Ferrochrome (Fe Cr) is an alloy of chromium and containing between 50% and 70% chromium.
Ferrosilicon� is an alloy of iron and silicon that is made by reducing silica in the presence of iron, and which plays an essential role in steelmaking.
Silicon iron, also known as ferrosilicon, is a ferroalloy composed of iron and silicon, with a silicon content ranging from 15% to 90%. It is commonly used as a deoxidizer in steelmaking and as a reducing agent in ferroalloy production and the chemical industry. In the steelmaking industry, approximately 3-5 kg of 75% ferrosilicon is consumed to produce one ton of steel. Ferrosilicon can also be used as an alloying element additive, which is widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel.
Ferrosilicon is also used in the production of cast iron, as it helps to control the initial content of silicon in the melt, which is important for the microstructure and properties of the final product. Ferrosilicon cast magnesium is an alloy that contains magnesium and is used as a nodulizer in the production of ductile iron. It has a big mechanical strength, and the effect of deoxidization and desulfurization is strong. Modifiers are added to molten metal to change its properties, and ferrosilicon is one of the most commonly used modifiers in the production of cast iron. The material forming the base Ferrosilicon analysis ferrosilico cast magnesium and modifiers.
The role of Ferrosilicon in Steelmaking:
In steelmaking, Ferrosilicon is used for:
We offer superior quality sponge iron that is also known as direct- reduced iron. Our offered sponge iron is made for high grade, 65-70 fe
Min fem-80%, fet-90-92%, s-0.04% max. Loose in form of lumps.
Sponge iron filter material In industry through a sponge iron production equipment is widely applied iron phosphorus reduction method, method of reduction of iron ore concentrate, etc., the rolling iron phosphorus or ore concentrate after reduced iron press down into pieces, into the roasting tube into the kiln roasting, produce the high quality reduced iron. Sponge iron filter material for the first time into the deaerator, must first after backwashing, remove the sponge iron residue on the surface of the filter material float ash impurities.
Silicon monoxide, white cubic crystal or brown powder, is insoluble in water, soluble in a mixture of dilute hydrofluoric acid and nitric acid, reacts with boiling caustic soda solution to form silicate and hydrogen, can be oxidized by halogens, and is easily oxidized in the air to form a protective film of silicon dioxide and become inactive. It has strong reducing properties at high temperatures and can reduce water vapor, carbon dioxide, limestone and other substances; it is often obtained by sublimation of silicon dioxide and elemental silicon powder in a high vacuum above 1400�°C in industry; it is often used to prepare optical glass and semiconductor materials.
Uses Used to make optical glass and semiconductor materials. The overview, physical and chemical properties, preparation methods, and uses of silicon monoxide are edited and compiled by Ding Hong of Chemicalbook (2015-11-16) Chemical properties White cubic or loess-colored amorphous powder. When heat-treated in air, the loess-colored powder turns into white powder. Melting point is greater than 1702�°C. Boiling point is 1880�°C. Relative density is 2.13. Insoluble in water, Chemicalbook is soluble in a mixture of dilute hydrofluoric acid and nitric acid. Uses Silicon monoxide powder is extremely active and can be used as a raw material for the synthesis of fine ceramics, such as silicon nitride and silicon carbide fine ceramic powder raw materials. Uses Used in the preparation of optical glass and semiconductor materials Uses As a raw material for fine ceramics, it has important value. It can also be evaporated in a vacuum and applied to the metal reflector used in optical instruments as a protective film. It can also be used to manufacture semiconductor materials. It is also used in optical glass.
Silicone rubber surfactant (Organic silicone surface additive) Application:
It can be used as a spray modifier, foliar absorption aids, activation agent, widely used herbicide, liquid nutrients, growth regulators, insecticides, fungicides, which do not decompose the original pesticide, can greatly reduce the surface tension of the solution, reducing the contact between the droplet and the leaf angle, surface enhanced the liquid in the plant or pest surface wetting, adhesion, and a spreader, thereby improving efficacy.
Silicone surfactant ZINCA-2000 is lower phytotoxicity and environmental hazards than the normal fatty amines, ethoxylated alcohol surfactant, and greatly reduce human and environmental impact.

Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc.
