The offering is fused silica sand with a chemical purity of 99.7 % SiO₂, produced to meet industrial standards for high‑temperature applications. Available grain size ranges include -10 + 20 mesh, -30 + 50 mesh and -50 + 100 mesh, allowing selection based on specific process requirements. The sand exhibits an extremely low coefficient of thermal expansion, which helps maintain dimensional stability during heating cycles. Consistent chemistry and controlled particle size distribution make it suitable for precision casting and glass production.
In the refractory and glass‑making sectors, typical bulk density for fused silica sand is around 1.5 g/cm³ and moisture content is kept below 0.1 % to avoid defects. Particle shape is usually angular to sub‑angular, providing good flowability and packing efficiency. Standard sieving tolerances are ±5 % of the nominal mesh size, ensuring uniformity across large batches. These industry‑standard characteristics aid buyers in designing formulations and process parameters.
The sand is primarily purchased by foundries, glass manufacturers and advanced ceramics producers that require low thermal expansion and high purity. The supplier can provide bulk quantities, but the exact minimum order quantity and production lead time are not listed and should be confirmed directly. Shipping options include FOB from the nearest Indian port or CIF to the destination, with certifications such as ISO 9001 or ASTM standards available upon request. Buyers are advised to verify the mill test report before finalising the contract.

Prior to ordering, ask for a mill test report that details the 99.7 % SiO₂ purity and the exact mesh size distribution for the batch. Confirm the supplier’s harbor trust tier and the address in Gautam Buddh Nagar, Uttar Pradesh, and request photographs of the storage facility to assess hygiene conditions. Because the listed response rate is zero, obtain a dedicated sales contact and a written commitment to reply within a specified number of hours.
Agree on the Incoterm that best fits your supply chain, for example FOB Hazira or CIF Mumbai, and ask the supplier to provide an estimated production lead time after the purchase order is accepted. Payment is usually arranged via a confirmed L/C or TT, but the precise terms should be documented in the contract. Clarify whether the sand will be loaded in bulk containers or in 25 kg polypropylene bags, as this influences freight calculations.
Plan for a pre‑shipment inspection to verify particle size distribution, bulk density and moisture content against the typical values stated. Request the inspection
