Rand Rock Minerals Pvt. Ltd. supplies Glassy High Purity Quartz Lumps, an industrial mineral used where silicon purity is critical. The chemical analysis shows silicon dioxide content of 99.89 % with aluminium oxide below 50 ppm, iron below 2 ppm, calcium under 6 ppm, magnesium under 1 ppm, and trace amounts of boron, sodium, phosphorus, lithium and titanium each below 2 ppm. Electrical conductivity is measured at less than 5 µS cm, indicating very low impurity levels. The lumps are delivered in bulk form, suitable for further processing into wafer or crucible material.
In semiconductor and solar wafer manufacturing, quartz material with SiO2 purity above 99.5 % is the standard baseline for achieving high yield. Typical lump dimensions range from 5 cm to 20 cm, allowing easy handling and crushing for downstream processes. Standard bulk packaging uses reinforced fibre bags of 20 - 25 kg capacity, sealed to protect against moisture ingress. Moisture content is usually kept below 0.1 % by weight to prevent hydrolytic defects during crystal growth.
Major users include semiconductor wafer producers, photovoltaic cell manufacturers, optical glass makers and specialty ceramics firms. Buyers such as integrated circuit fabs, solar panel assemblers and research laboratories often place repeat orders to maintain consistent feedstock quality. Rand Rock Minerals indicates flexible bulk quantities and offers FOB or CIF shipping from Hyderabad, but exact minimum order quantities and lead times must be verified with the supplier.

Sourcing Glassy High Purity Quartz Lumps from Rand Rock Minerals Pvt. Ltd. - India Import Guide
Importers should first obtain the full chemical analysis report, confirming SiO2 purity, impurity limits and electrical conductivity, and request any available ISO or ASTM certificates. Verifying the lump size distribution and moisture content is also critical to ensure the material meets downstream processing specifications.
Shipping is typically offered on FOB or CIF terms from the Hyderabad port. Because the supplier’s response rate is recorded as zero, buyers should establish a clear communication protocol, agree on lead‑time estimates, and define payment milestones such as a T/T deposit against a pro‑forma invoice followed by balance payment upon presentation of shipping documents.
A pre‑shipment inspection by an accredited third‑party laboratory is recommended to validate the chemical composition, impurity levels and moisture content. Importers should retain the inspection report, the supplier’s test certificates and the commercial invoice to facilitate customs clearance and to support any warranty claims after delivery.
