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: Is the ordinary glass component silica or silicate?: A relatively transparent solid substance that forms a continuous network structure during melting; a silicate like nonmetallic material with increasing viscosity and hardening without crystallization during cooling. Widely used in buildings for wind and light transmission; of mixtures. Silicates can be written in the form of oxides, such as Al2O3 ? SiO2.Ordinary glass according to high school teaching materials, you can think that the main ingredient is SiO2.(Note: if it is deeper, it can be considered as Na2O CaO 6SiO2, of course, in fact, glass is a mixture and has many other ingredients. (quartz glass is generally believed to be the main component of SiO2)

Q: Does the dust produced in the manufacture of abrasive wheels contain silica?: Yes, we haveFree silica is the major cause of pneumoconiosis.If it is long-term work, it is recommended to use high-grade respirators to prevent lung disease.

Q: How much acid does silica use to become mesoporous silica?: We used 30% hydrofluoric acid to etch the sample in an ultrasonic environment. In this case, it is necessary to seal the container, because the concentration of 30% hydrofluoric acid is relatively high, and the volatility is stronger. You can have a try

Q: Silica, diamond, graphite, sulfur, phosphorus, and the number of covalent bonds in the cause of red phosphorus: Silicon dioxide and silicon oxygen tetrahedron space arrangement, each oxygen atom has two covalent bonds to connect silicon atoms, a silicon atom has four covalent bonds to connect oxygen atoms. Therefore, there are 4mol covalent bonds.

Q: What is the difference between silica and reactive silica?: Silica dioxide plays an important role in daily life, production and scientific research, but sometimes it can cause harm to human body.

Q: Can silica in a drier make a sole?: You can dissolve the silicic acid with sodium hydroxide solution, and then add hydrochloric acid to obtain the silicic acid colloid.

Q: Why can remove polysiloxane, silica: Uniform skin tone APSC multi cell treatment of scars, but also improve the skin texture of the scar, to prevent the skin and subcutaneous scar tissue re adhesion, no trace, and uniform skin tone. Improve scar local skin, treatment of scars at the same time, local also can appear soft skin, elasticity and gloss increase, pigmentation reduce, scar hidden, and so on.

Q: What role does silicon dioxide play in integrated circuits?: Then, doping at high temperatures (e.g. boron doped) allows boron to diffuse into this region without silica protection, thus becoming a P type region (usually the base region)

Q: The food additive has "silica dioxide", can you eat it?: It is an odorless, tasteless, no biological activity of white powder, eat even after the reaction with acid can affect human body cannot become the normal work of the material. The majority should be directly through the feces with urine directly out of the body.

Q: Compared with carbon black, what kind of properties do the white carbon reinforce?: In the tire, compared to carbon black, white carbon can reduce rolling resistance, it is clear that it can save oil. In addition, white carbon reinforced tires generate low heat at high speeds. As for the disadvantages, they are not wearable.
