Fused Silica
The product is fused silica supplied by Xinju Import & Export Dalian Co., Limited in China. It is a high‑purity SiO₂ raw material with typical purity of 99.5 % or higher. Grain sizes are offered in ranges such as 0.25‑0.4 mm, 0.4‑0.6 mm, 0.8‑1 mm, 1‑3 mm and 3‑5 mm, while powder forms are available at 200‑mesh and 325‑mesh with a D50 of about 12 µm. The supplier lists these variations to meet the precise requirements of different industrial processes.
In the refractory and precision‑casting sectors, fused silica is valued for its low thermal expansion and excellent chemical resistance. Typical industry grades are defined by particle size, with finer grades used for glass‑ceramic moulds and coarser grades for refractory linings. Standard specifications call for moisture content below 0.05 % and bulk density around 2.2 g/cm³. The supplier notes that the material can also serve as a sound‑dampening filler in industrial paints, reflecting its versatility across high‑performance applications.
Key buyers include foundries, ceramic producers, chemical plants and manufacturers of electrical appliances that need consistent silica quality. Trade is generally performed under FOB or CIF terms, with packaging in bulk bags or sealed drums as agreed with the purchaser. Since the listing does not disclose MOQ, price or exact lead time, the importer should request these details directly from Xinju Import & Export Dalian Co., Limited.

Sourcing Fused Silica from Xinju Import & Export Dalian Co., Limited - China Import Guide
Start by confirming the silica’s chemical purity and grain‑size distribution through a recent certificate of analysis. Verify that the moisture content meets the typical limit of less than 0.05 % and that the bulk density aligns with the values required for your processing equipment. Checking the supplier’s harbour trust tier and asking for any third‑party audit reports will give additional confidence before committing to a purchase.
Discuss the preferred Incoterm, such as FOB Dalian or CIF Shanghai, and agree on the exact port of discharge. Because lead‑time information is not listed, request a realistic delivery schedule based on the order volume and packaging type. Clarify the payment method - for example, T/T against documents or a confirmed L/C - and any required advance deposit.
Arrange for a pre‑shipment inspection, either at the supplier’s facility or by an independent agency, to validate particle size, bulk density and moisture content. Request test reports that reference recognised standards such as ASTM C‑1499 for silica purity. Maintaining complete documentation, including the material safety data sheet and customs declaration forms, will facilitate smooth clearance and reduce the risk of delays.
