What is silica powder?
Silica powder is finely crushed silica. It is pure silicon dioxide. Silica is typically quartz that has been finely ground into a fine white powder. The thickness of ground silica powder and the size of the mesh used in the processing determines the fineness of the powder and the amount of fine silica powder in will be in the bag. The quality of the silica can be determined by the purity levels, whiteness and consistency of the powder particles. The silica powder produced at Sudarshan group achieves a SiO₂ content of 99%-99.5%. Purity levels are superior to other powder suppliers in the industry. Sudarshan offers a variety of sized mesh for any industrial need. The silica powder manufactured at Sudarshan gives you the same quality every time. Whether you are looking for an industrial grade silica powders or an ultra-pure grade, the consistency and superior quality are what keeps a steady stream of orders flowing.

Applications and Uses of Silica Powder



Glass Industry
It serves as the main raw material for manufacturing flat glass, container glass, and specialty optical glass products.


Electronics Industry
Silica powder is essential for semiconductor manufacturing, solar panel production, and electronic component insulation.


Ceramics Industry
Silica powder provides strength in ceramic tiles, sanitary ware, and heat-resistant products while enhancing durability.


Construction Industry
Silica powder increases the strength of concrete by 15-25%, provides improved durability, and reduces water penetration.


Paints and Coatings Industry
Silica powder functions as an additive in protective coatings while improving scratch resistance, thermal protection, and UV stability.


Cosmetics Industry
Silica powder is used as an anti-caking agent, flow improver, and absorbent in cosmetic formulations for enhanced texture and stability.
The usage of silica powder in construction: Real-World Application

Currently, construction is the dominant way that silica powder is used in the world, and this is important because when engineers utilize silica powder in concrete, it participates in a pozzolanic reaction with calcium hydroxide, which is formed during hydration of the cement. This reaction generates more calcium silicate hydrate compounds in the concrete that fill microscopic voids in the concrete structure. Stronger concrete is the result.
Concrete that contains silica powder has an increased compressive strength of 15-25%. Structures also come with a reduced permeability to water, which increases the expected lifespan of concrete structures in harsh conditions by 20-30+ years. More engineers around the world are using concrete that has silica powder in bridges, tunnels, and high-rise buildings. Marine structures subjected to saltwater exposure show an increase in resistance to chloride exposure, reducing the likelihood for corrosion on steel reinforcements. Furthermore, precast concrete products benefit from silica powder as they demonstrate early-age strength, providing precasters with a quicker production turn-around. Industrial flooring systems maintain structural integrity even when subjected to heavy machinery traffic, without cracking.
