Introduction

The nano silica market is expanding rapidly as industries seek innovative materials that enhance performance and sustainability. Nano silica, or silica nanoparticles, are ultra-fine particles with unique chemical and physical properties. Their ability to improve strength, durability, and functionality has made them an essential material in construction, paints, plastics, healthcare, and energy applications. According to Stratview Research, The nano silica market was estimated at USD 3.72 billion in 2021 and is likely to grow at a CAGR of 6.08% during 2022-2028 to reach USD 5.63 billion in 2028.

Key Features

Nano silica exhibits high surface area, thermal stability, and strong mechanical reinforcement capabilities. It improves bonding in composites, reduces shrinkage, and enhances abrasion resistance. Both hydrophobic and hydrophilic forms allow flexibility in usage across diverse industrial environments. Additionally, its small size and chemical reactivity make it suitable for functionalized applications in advanced coatings and biomedical products.

Applications

Construction is a major consumer, where nano silica is added to concrete to increase compressive strength, durability, and resistance to environmental damage. In coatings and paints, it improves hardness, weather resistance, and gloss. Electronics use nano silica for insulation, while the rubber and plastics industries rely on it for improved elasticity and wear resistance. Healthcare employs it in drug delivery, dental care, and biomedical devices, while agriculture uses it to enhance fertilizers and crop protection products.
