Industrial Commodity
Specialty Silicas from Algeria
Specialty silicas are the grades a process specification actually constrains: particle size, purity, iron, whiteness. They are not the bulk silica cargo.
What is Specialty silica?
Specialty silicas (silices spéciales) cover finer flours, tighter size cuts and higher-purity silica than a standard sand shipment. Uses include fillers, selected glass, coatings and other industrial processes. If you need silica sand or lump in a 5,000 to 30,000 tonne cargo, start from the silica page.
How we source Specialty silica
Send the cut or d50, the purity or iron ceiling, the use, the volume and the destination. We only move to price when a grade looks reachable.
Typical applications
- Industrial fillers and extenders
- Higher-spec glass and ceramics
- Coatings and process silica
Technical specifications
Particle size, SiO2, iron, moisture and whiteness where relevant are confirmed on the grade. A bulk sand analysis does not stand in for this.
Logistics & packing
Big bags and containers are the usual conversation. Bulk is possible when the grade and the volume both allow it. We do not apply the industrial-bulk cargo bracket to these grades by default.
Big bags, bags or containers, chosen so the cut survives handling. Bulk only after that is shown to be workable.
Documents & inspection
Particle-size and chemical data for the selected grade, plus commercial and export papers.
Independent lab checks on size and chemistry can be arranged before shipment.
Commercial terms & export
Quoted per grade. A buyer who only needs bulk sand is redirected to the silica line rather than stretched onto a special cut.
Grade targets → supply match → packing → documents and shipment.
Frequently asked questions
From the desk
Longer notes on specialty silica for buyers who want the context before they send a brief.
Silica sand or silica flour: two cargos that should never share a contract
Silica sand in a bulk industrial cargo and silica flour in big bags are different products. Split the brief, the packing and the contract before anyone talks price.
Calcium carbonate filler or silica filler: which brief to send
Send a carbonate formula to the calcium carbonate line and a silica flour to specialty silicas. If the mineral is still unnamed, start from industrial fillers and the process tests.
Specialty silica grades: cut, iron and when the brief is really a filler
A specialty silica grade is the cut and the iron level the process asks for, confirmed on the lot and packed for bags or containers. A carbonate filler brief belongs on another page.
Bulk silica sand: cargo, contamination and when to leave this page
How a silica sand supplier books bulk cargoes: import silica sand, parcel size, moisture, stowage and contamination from the previous cargo.
