Description of acticel
- Synthetic Amorphous Silica has interesting thickening and thixotropic properties, and an enormous external surface area. It is produced by a vapor phase hydrolysis process using chlorosilanes or substituted silanes such as, silicon tetrachloride in a flame of hydrogen and oxygen. This material is formed and collected in a dry state. This product contains no detectable crystalline silica.

What is Silica, fumed ?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Silica, fumed which has developed particularly rapidly in recent years. Do you know about Silica, fumed?
- The official answer：Chemically stable. It is insoluble and does not react with water. It is an acidic oxide and does not react with common acids. Gaseous hydrogen fluoride reacts with silicon dioxide to form gaseous silicon tetrafluoride. Reacts with hot concentrated alkaline solutions or molten alkalis to form silicates and water. Reacts with various metal oxides at high temperatures to form silicates. It is used in the manufacture of quartz glass, optical instruments, chemical vessels, general glass, refractory materials, optical fibers, ceramics, etc. Silicon dioxide is not reactive, it does not interact with halogens other than fluorine and hydrogen fluoride, hydrogen halides, as well as sulphuric, nitric, and perchloric acids (except hot concentrated phosphoric acid). The common concentrated phosphoric acid (or pyrophosphoric acid) can corrode silicon dioxide at high temperatures, generating heterogeneous acids [2], and fused borates or boric anhydride can also corrode silicon dioxide at high temperatures, given this property, borates can be used as fluxes in ceramic firing, in addition to hydrogen fluoride can also make silicon dioxide dissolved acid, generating water-soluble fluorosilicic acid: SiO₂+4HF=SiF4↑+2H₂ O.
What’s the application of Silica, fumed ?
- Widely used in a variety of coatings, plastics, adhesives, and sealants, in rubber as a reinforcing agent used in the manufacture of water glass, refractory materials, optical glass, optical fibers, quartz glass instrument raw materials, can also be used for the manufacture of ultrasonic components, adsorbents and other uses for electronic packaging, oversized integrated circuits, advanced ceramics, ink industry uses for picture tubes, projection tubes, oscillator tubes between the glass plane and phosphor It is used as a dehumidifying and drying agent, dehydrating agent, moisture-proof agent, and air humidity regulator. Also used for drying of gases. It is also used as a catalyst and catalyst cutter, a reinforcing agent for silicone rubber, and a sizing agent for the textile industry.
