Microsilica can be used in a variety of cementation products, such as concrete, grouts, and mortars as well as elastomeric, polymer, refractory, ceramic and rubber applications.
We collect micro silica from our own 16 ferro silicon furnaces. Monthly we collect approx. 2000 MT micro silica with Sio2 85-94%

Silicon Dioxide Classification fumed

Q: Why SiO2 have two kinds of crystal and non crystal? How do I get it?: SiO2 uses two forms of existence in nature: one is crystalline, such as crystals, diamonds, etc., similar to precious stones, having regular shapes, fixed boiling points, and all the properties of crystals. One is non crystalline, such as silica glass, similar to glass, irregularly shaped, with no fixed boiling point, and conforms to amorphous properties.

Q: What is the main principle of rapid determination of silica by ammonium chloride gravimetric method?: Silicate particle in the acid solution is a strong hydrophilic colloid, with a negative charge, ammonium chloride is a strong electrolyte, the existence of positively charged NH4+ in heating evaporation under the condition of positive and negative charge, so as to accelerate the polymerization of silicic acid, causing precipitation.

Q: What is the indicator mineral of unsaturated silica in magma?: Silica is one of the most important rock forming components, it and other rock forming components with formation of olivine and pyroxene, hornblende, mica, feldspar and other minerals. These minerals in the formation of silica is still excess (i.e. supersaturation), so there will be quartz, quartz is igneous rocks indicated silica mineral saturation; if there may be insufficient silica content of olivine or feldspar minerals (such as nepheline). When silica and other rock group moderate content, it does not appear the two kinds of minerals, and the formation of pyroxene, amphibole and feldspar, silica saturated minerals.

Q: How does silica naturally form?: Pure quartz is a colorless crystal, large and transparent, prism like quartz called crystal. If they contain trace impurities in crystal with different colors, amethyst, Citrine, topaz etc.. Ordinary sand is quartz fine sand, a (iron impurity) and white sand (less impurities, Jiao Chunjing).

Q: What effect does silica content have on cement properties?: At the same time also have an impact on the silica content of clinker, high silica content, liquid amount, calcination is difficult, will increase the heat consumption of clinker, easy powder; low silica content, liquid volume, easy to form large, affecting the operation.

Q: What materials do you have instead of silica powder?: According to the guide light transmittance is divided into several. The most typical is silica, but the brightness of the silica has not been ideal for addition to the resin. There are many developed new conductive powder, haze higher, higher brightness. Better than silica.

Q: What are the raw materials for the production of precipitated silica?: The sodium sulfate impurity is removed by the process, and the partial silicic acid is unstable and is broken down into silica and water, and the water is dried, and the residual silica is white carbon

Q: How does silica become crystalline?: Silica widely exists in nature, and other minerals constitute the natural silica rock. There is also called silica, is a kind of solid hard refractory silica. Also called silica, chemical formula SiO. Nature exists in two crystalline silica and amorphous silicon oxide two.

Q: Does anyone press the glass on the front of the glass? Is it easy to install?: The flux is generally containing sodium oxide, potassium oxide, lead oxide, calcium oxide, barium oxide and other materials, such as limestone, feldspar, sodium carbonate, boric acid, lead compounds, barium compounds. (sodium oxide can reduce the viscosity of glass forming, the glass is easy to melt, plays a good role in flux; barium oxide in glass the formation plays a basic role with sodium oxide; tin oxide can increase the glass chemical stability and mechanical strength; lead oxide can increase density, improve hunting, with special luster; lead can make a glass of light refraction and scattering rate of small glass makes more lustrous and stable.

Q: What is the ceramic made of silica? What's the use of it?: The silica used for ceramics is silica. Silica is widely used, mainly for the manufacture of glass, water glass, pottery, enamel and refractory materials.
