The product is refractory quartz sand supplied by Gongyi City Hong The Refractory Material Co., Ltd., sourced from Henan province in China. It consists of high‑purity quartz (SiO2) with a measured SiO2 content of 97.5 % and minor oxides such as Al2O3 (0.7‑0.3 %), Fe2O3 (0.4‑0.1 %) and moisture up to 0.5 %. The bulk density ranges from 1.9 to 2.1 g cm‑3 and the liner volume density from 1.75 to 1.8 g cm‑3. Particle size is offered between 5.1 mm and 0.021 mm, covering typical mesh grades for refractory applications.
Quartz sand of this grade is valued for its thermal stability, low thermal expansion and resistance to acid attack, properties that align with standard refractory material requirements. Typical industry specifications call for a SiO2 purity above 96 % and a bulk density near 2.0 g cm‑3, which this product meets. The material’s melting point of approximately 1750 °C enables use in high‑temperature environments such as steel‑making induction furnaces. Standard processing yields a milky‑white, translucent crystal with conchoidal fracture and an oily luster, matching the visual criteria for refractory sand.
Major users include foundries, glass manufacturers, ceramic producers and steel‑plant furnace lining contractors who require consistent particle size distribution and chemical purity. The supplier offers bulk shipment for immediate import, with packaging typically in sealed bulk bags or ocean‑freight containers, though exact MOQ and incoterms should be confirmed directly. Buyers should verify the supplied analysis report, certify that the mesh size matches their furnace design, and request a sample batch for trial melt runs. Payment and delivery terms are negotiated per order, with the supplier’s harbor trust tier indicating a verified trade record.

Before placing an order, importers should request the latest certificate of analysis that confirms SiO2 purity, bulk density and moisture content. Cross‑check the particle‑size distribution against the mesh grade required for the intended furnace design. It is also prudent to ask for a recent batch sample and for the supplier’s export compliance documents, such as a material safety data sheet. Verifying these details reduces the risk of receiving material that deviates from specifications.
The supplier indicates bulk shipment capability, but specific incoterms, lead‑time and freight options are not listed and must be negotiated. Importers typically arrange ocean freight in 20‑ft containers, with the option of FOB or CIF terms depending on the buyer’s preference. Payment methods are usually agreed per contract; common practice includes a letter of credit or advance payment, subject to the buyer’s risk assessment. Confirm these terms in the purchase agreement.
For quality assurance, buyers often engage a third‑party inspection agency to verify the chemical composition and particle size on arrival. Request the supplier’s quality management certificates, such as ISO 9001, if available, and ensure that the packing is sealed to prevent contamination. Documentation should include a packing list, commercial invoice and the analysis report, which together facilitate customs clearance and downstream processing.
