SILICA GRAINS
& POWDER
High purity silica grains and finely graded quartz powder — sourced from the finest quartzite mineral belts in eastern and western India, processed to your exact specifications.
SILICA
GRAINS
"Precisely graded, consistently pure — the building blocks of high-performance refractory lining."
PSM Orechem sources and supplies custom graded Silica Grains — also known as Quartz Grains — engineered for use in refractory making. Drawn from select quartzite deposits in Jharkhand (east) and Rajasthan (west), each batch is crushed, washed and screen-graded to the particle distribution your formulation specifies — with SiO₂ > 97.5%, Fe₂O₃ < 0.20% and Al₂O₃ < 0.30%.
Our Silica Grains are available in a grading range of 0.5mm to 2.5mm, as a single fraction or a blended gradation. The same grains form the skeleton of our own ramming mass grades, so the screening discipline you get here is the one our own product line depends on.
QUARTZ
POWDER
"Finely milled, tightly controlled — precision powder for demanding industrial applications."
PSM Orechem supplies finely graded Quartz Powder processed from high purity quartzite through controlled milling and classification. Our powder is available in mesh sizes from 200 mesh to 325 mesh, ensuring the precise fineness required for your specific application.
All mesh sizes are available as per customer requirements. Our process maintains tight particle size distribution with minimal oversize or undersize fractions, delivering the consistency that industrial processes depend on.
WHERE OUR SILICA GOES
The same quartzite, three destinations. Which form you need depends on what you make.
Graded grains (0.5–2.5 mm) form the aggregate skeleton of ramming masses, castables and patching compounds. We blend single fractions or full gradations to your sieve analysis.
If you line furnaces rather than make refractories, you want the finished product: our three ramming mass grades are built on these exact grains. The full story is on The Science page.
200–325 mesh quartz powder for glass, ceramics, foundry coatings and filler applications where particle-size discipline and low iron decide the batch quality.
