ORIENT PARTNERS RESOURCES

An essential material. Different requirements for every industry.

As quartz, sand or flour, silica enters numerous industrial value chains. SiO₂ content matters, alongside impurities, particle size and behaviour in your process.

Silica & grades

Different grades

Raw, classified sand, grains or flour: format and treatments are confirmed in the quote.

Application qualification

Define SiO₂, iron, alumina, moisture, grain size and functional tests.

OPR supply

Discuss samples, volume, frequency, packaging and destination.

From specification to approved material

Define the application

Start with your process and operating constraints.

Set specifications

Identify moisture, particle size, chemistry and functional tests.

Arrange trials

Agree on a sample and test protocol before approval.

Build the offer

Confirm price, availability, packaging, transport and timing by quotation.

The OPR silica journal

GUIDE / 01

High silica content versus high purity

Specify SiO₂ and limits for Fe₂O₃, Al₂O₃, TiO₂, alkalis or other elements for your process. Lot values require analysis.

GUIDE / 02

Iron and particle size: two key criteria

Combine suitable chemistry and, where useful, XRD phase identification. Define analytes, detection limits, dry basis and units.

GUIDE / 03

Prepare a silica specification for OPR

Provide sample mass, required analyses and acceptance protocol. Confirm cost, availability and shipment before dispatch.

Your silica enquiry to OPR

Every application needs a suitable grade and testing. OPR confirms grades, processing and availability; no ultra-high-purity grade or certification is assumed.
