Silicon Dioxide, with the CAS number 112945-52-5, is a widely used inorganic compound known for its white, powdery appearance and high purity. Understanding its properties and adhering to safe handling practices is crucial for anyone working with this versatile chemical. NINGBO INNO PHARMCHEM CO.,LTD., a reputable manufacturer and supplier in China, provides detailed information to ensure the safe and effective use of our Silicon Dioxide products.

Physically, Silicon Dioxide is characterized as a fine white powder. It has a high melting point, exceeding 1700°C, indicating its thermal stability. Its solubility in water and most organic solvents is very low, making it suitable for applications where inertness in aqueous or organic media is required. The molecular formula is SiO2, with a molecular weight of approximately 60.08 g/mol. Common synonyms include amorphous silica, fumed silica, and pyrogenic silica, reflecting its production methods and structural characteristics. These properties make it a valuable component in a wide array of industrial applications.

When handling Silicon Dioxide, it is important to be aware of its safety profile. While generally considered inert and non-toxic when ingested in moderate amounts, inhaling fine silica dust can cause respiratory irritation. Prolonged or high-level exposure to respirable crystalline silica dusts is associated with serious lung diseases like silicosis and potentially cancer, although the amorphous form is less fibrogenic. Therefore, it is recommended to use appropriate personal protective equipment (PPE), such as gloves, safety glasses, and respiratory protection (e.g., a dust mask) when handling the powder, especially in areas where dust may be generated. Good industrial hygiene practices, including adequate ventilation and avoiding dust generation, are essential. Proper handling ensures that the benefits of this chemical can be realized without compromising worker safety.

Storage of Silicon Dioxide should be in a cool, dry, and well-ventilated area, in tightly sealed containers to prevent moisture absorption, as it can be hygroscopic. By understanding these properties and following recommended handling and storage procedures, users can maximize the utility of Silicon Dioxide.
