Nanosilica or silicon dioxide nanoparticles, one of the materials fueling the field of nanomaterials, can be derived by dissolving olivine in acid. Nanosilica finds applications in biomedical research due to its low toxicity, high stability, and capability to be combined with a wide range of polymers & molecules. It is widely utilized in healthcare & medicine, rubber, plastics, food, electronics, agriculture, cosmetics, battery, gypsum, concrete, and others.
Versatile Applications of Nanosilica
· As a non-toxic and stable platform for biomedical applications like theranostics & drug delivery
· As a supporting filler for concrete and other construction composites
· As an additive for plastics and rubber
Olivine Silica Production
Neutralization of waste acids like hydrochloric or sulphuric acids with olivine produces custom-made nano-silica. The pH, olivine-specific surface area, and temperature determine the dissolution rate of olivine. This process can produce a large quantity of Nano-silica at low costs. It is one of the most sustainable techniques.
Advantages of Olivine Nano-silica
This product has the ability to substitute cement, which is the costliest component that is also hazardous for the environment, in concrete. Nano-silica can decrease CO2 footprints of the concrete products and can enhance its chemical properties when hardened. Thus, it can be used as a concrete that is cheaper, more effective, and environment-friendly.
Market Insights:
According to a report by Grand View Research, Inc.; the worldwide global nanosilica market is expected to surpass USD 5 billion by 2025. Rising usage of nanosilica as additive can boost the market over the forecast period (2014 to 2025). High end-use applications and awareness regarding degradability and bio-based products can further support the expansion. In addition, growing awareness for nanosilica intermediary products can also augment the growth over the next few years.
NanoPore Inc.; E. I. du Pont de Nemours and Company; Dow Corning Corp.; and Fuso Chemical Co. Ltd. are some of the key companies operating in the global market.
