High-Purity Silica Sand for Industrial Excellence
When it comes to industrial raw materials, purity isn’t a luxury—it’s a necessity.”
Silica Sand, also known as industrial sand, is one of the most widely used materials in the world. Composed primarily of Silicon Dioxide (SiO₂), it is formed from naturally occurring quartz and is one of Earth’s most abundant minerals, formed over millions of years through geological processes.
At Uma International Tradelink, our Silica Sand is derived from rich, high-purity deposits in India, known for their exceptional brightness, low moisture, and consistent chemical stability. Its fine composition, inert properties, and high thermal resistance make it a critical material across industries—from glass manufacturing and foundry casting, to water filtration, construction, and ceramics.

Clarity begins with purity—glass starts with exceptional silica.
Glass Grade Silica Sand is the cornerstone of high-quality glass manufacturing. It is primarily composed of very high-purity quartz (SiO₂ > 99%) and is meticulously processed to meet strict chemical and physical requirements. The defining characteristic is its low iron content, which prevents discoloration and ensures a clear, bright finish—essential for products like optical glass, containers, float glass, and solar panels.
UMA INTERNATIONAL TRADELINK sources its glass-grade silica sand from selective high-silica quarries. Through precision washing, drying, and sieving processes, we ensure uniform grain size, minimal impurities, and moisture-free product—ideal for melting without contamination.
Key Properties :
-
SiO₂ content typically Min 99% -
Low Fe₂O₃ (< 0.03%)
-
Uniform particle size distribution
-
Moisture-controlled & contaminant-free
Typical Applications:
Float & Sheet Glass Manufacturing
Delivers high SiO₂ purity (>99%) and ultra-low iron content (<0.03%) to ensure maximum light transmission, optical clarity, and structural strength in clear architectural glass.
Container Glass – Bottles, Jars, and Packaging

Consistency under heat—performance under pressure.
Engineered for precision in metal casting, UMA INTERNATIONAL TRADELINK’s Foundry Grade Silica Sand stands up to extreme heat and dimensional demands. Designed specifically for ferrous and non-ferrous foundries, our sand ensures structural integrity and superior casting finish under high-temperature conditions.
With a melting point around 1700°C and excellent thermal shock resistance, it provides the reliability required in modern casting systems. Our grains are sub-angular to round, striking the perfect balance between compactability and permeability—ideal for green sand molding, resin-coated cores, and no-bake systems.
