About Silicon Dioxide
About Silicon Dioxide. Silicon Dioxide (a.k.a. SiO2, Precipitated Silica) is an amorphous form of silica (Silicon Dioxide), like silica gel and pyrogenic silica. It is a finely divided white powder, soluble in water, composed of aggregates with up to approximately 1 mm in diameter, generally made by precipitation of an alkaline metal silicate solution. Its production started in the 1940s, and, currently, Precipitated Silica has the greatest commercial importance among the three types of amorphous silica.
Precipitated Silica is produced on a commercial scale from aqueous alkali metal silicate solutions (e.g., water glass) and acids (e.g., sulfuric acid), usually via precipitation carried out in batch mode. It is worth highlighting that, depending on the manufacturing process, Precipitated Silica may be produced with different physical and chemical properties to meet specific requirements.
Silicon Dioxide Handling. Silicon Dioxide is a hygroscopic material, so in transportation and/or storage it absorbs water and undergoes slow changes in structure. Its transportation and storage should be done in hermetically closed containments (usually multi-layer paper bags and FIBCs - flexible intermediate bulk containers) and largely delivered as bulk products in bulk trucks, railcars, or silo containers. The silica can also be transported in pallets and loose bags. It is considered nontoxic and it is also not flammable and not highly reactive. No other special measures must be taken in transportation or storage, besides common sense for good housekeeping.
Silicon Dioxide Production. When it comes to production pathways, Precipitated Silica can be produced from aqueous alkali metal silicate solutions, like water glass, and acids, such as sulfuric acid, hydrochloric acid, and carbon dioxide. Raw materials and the respective production processes employed in the manufacturing of Silicon Dioxide are listed below.
- Sodium silicate + sulfuric acid (acidification)
Silicon Dioxide Uses. Precipitated Silica can be enhanced with different physical and chemical properties to meet specific requirements in such a way there are several different grades for it. For example, there are food, coatings, silicone rubber, and rubber grades. Typically, all these grades are commercialized with at least 95% SiO2 content, which can reach a high-purity level, such as 99.9% minimum content.
