Product Description
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 earths 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.

Key Features of Silicon Dioxide PowderThis silicon dioxide is presented as a white, amorphous powder with a granular size ranging between 5-200 m. Known for its chemically inert nature and a purity of at least 99%, it remains stable across varied industrial environments. Its physical characteristics include a high melting point (1710C), a neutral to slightly acidic pH (6-8 in a 5% solution), and a very low moisture and ignition loss, making it suitable for precise industrial uses.
Versatile Industrial and Laboratory ApplicationsSilicon Dioxide finds extensive use across many industries. Applications range from its role as a filler in glass manufacturing and ceramics, to its use in rubber and paint formulations. It is also commonly employed as an anti-caking agent and in the production of electronics. Its high purity and inertness ensure it does not alter end-product characteristics, making it valuable for demanding processes.
Safe Handling and Storage RecommendationsStore Silicon Dioxide in a cool, dry, and well-ventilated area inside tightly closed HDPE containers to prevent moisture absorption or contamination. With a shelf life of 2 years, it retains its properties when kept in proper conditions. The substance is non-toxic, tasteless, and odorless, ensuring safe handling for workers and users following standard industrial hygiene practices.
FAQs of Silicon Dioxide:
Q: How should Silicon Dioxide be properly stored to maintain its quality?
A: Silicon Dioxide should be stored in a cool, dry, and well-ventilated place inside tightly sealed containers, such as HDPE bags. This prevents moisture absorption and contamination, ensuring the powder remains effective and stable for up to 2 years.
Q: What are the primary industrial applications of Silicon Dioxide powder?
A: Silicon Dioxide powder is used in glass manufacturing, ceramics, rubber, paints, and electronics. It also serves as an anti-caking agent and is suitable for use in laboratory settings, offering high chemical inertness and stability in various formulations.
Q: When is it appropriate to use Silicon Dioxide in food or pharmaceutical processes?
A: When using Silicon Dioxide in food or pharmaceutical processes, ensure the product meets the appropriate grade standard for those applications. This specific product is suitable for food, pharmaceutical, and industrial uses, provided grade specifications are verified.
Q: Where does Silicon Dioxide demonstrate the most significant benefit in industrial processes?
A: Silicon Dioxide provides the greatest benefit in processes where chemical inertness, high purity, and filler properties are requiredsuch as glass and ceramics manufacturing, rubber compounding, or as an anti-caking agent in powder handling.
Q: What is the typical process for using this product in laboratory applications?
A: In laboratories, Silicon Dioxide is commonly used as a support matrix, filtration aid, or as part of sample preparation. Its inert properties ensure it does not interfere with chemical reactions, making it ideal for analytical and industrial research processes.
Q: How does the high purity and amorphous shape of Silicon Dioxide impact its usage?
A: The high purity (minimum 99%) and amorphous structure enhance compatibility across a broad spectrum of applications. These characteristics prevent undesirable chemical reactions and ensure consistent performance as a performance additive or process aid.
Q: What are the benefits of choosing Silicon Dioxide with these specifications for manufacturing?
A: Choosing this grade of Silicon Dioxide ensures consistent size (5-200 m), reliable bulk density, minimal moisture, and non-toxic properties, contributing to quality control, process efficiency, and safety in manufacturing operations.
