Fused Silica
Chem & Size Minerals Limited supplies fused silica, a high‑purity silicon dioxide material with a minimum purity of 99.9% SiO₂. The product is produced by electric fusion of natural crystal quartz, delivering a material that resists thermal shock and exhibits a low thermal expansion coefficient. The supplier lists the material as suitable for precision casting, optical glass, and semiconductor components.
Fused silica’s density of approximately 2.20 g cm⁻³ and its typical thermal expansion of 0.5 × 10⁻⁶ /K make it valuable where dimensional stability is critical. Optical transmission between 200 nm and 2500 nm is standard for this grade, supporting high‑performance lens and photonic applications. Industry practice also values its excellent chemical resistance to acids and bases, allowing use in harsh processing environments.
Typical buyers include manufacturers of optical lenses, semiconductor substrates, and high‑temperature insulation components. The supplier mentions flexible minimum order quantities and offers both CIF and FOB shipping options, but exact terms should be confirmed directly. Importers should request any relevant ISO or SGS certification documents before finalising the purchase.

Sourcing Fused Silica from Chem & Size Minerals Limited - China Import Guide
Before placing an order, importers should obtain a certified analysis report confirming the 99.9 % SiO₂ purity and request a sample for laboratory testing. Verifying the thermal expansion coefficient and grain size distribution helps ensure the material meets design tolerances. It is also advisable to ask for copies of any ISO or SGS certificates that the supplier can provide.
Chem & Size Minerals Limited offers both CIF and FOB terms from the port of Lianyungang, but exact Incoterms and shipping schedules must be confirmed with the supplier. Because the response rate is currently recorded as zero, buyers should establish a clear communication channel and request a written quotation outlining freight charges, insurance, and any handling fees. Lead times are not published and should be negotiated before contract signing.
During production, buyers can arrange third‑party inspection to verify particle size distribution, density, and absence of foreign material. Typical inspection standards include ASTM D 563 for bulk silica and ISO 17025 for laboratory testing. Request the supplier’s test certificates and a material safety data sheet to complete the documentation package required for customs clearance and downstream processing.
