Fused silica , fused quartz, silica powder
The product is fused silica, also described as fused quartz or silica powder, supplied as grains and fine powder with a silicon dioxide purity ranging from 99.5 % to 99.99 %. The material contains iron oxide (Fe₂O₃) limits of 15 ppm maximum to 50 ppm maximum and is offered in a broad spectrum of particle sizes from 0.1 mm up to 3 mm for grains and multiple mesh grades for powder. Packaging is typically provided in 25 kg paper bags or 1 ton bulk bags for export handling.
Sinoteng offers both fused silica grains and micro‑silica powder, as well as crystalline silica sand, allowing customers to select grades that meet the requirements of investment casting, refractory linings, advanced ceramics and artificial marble composites. In the industry, a common specification for high‑grade fused silica is a minimum purity of 99.9 % and Fe₂O₃ content below 20 ppm, which aligns with the supplier’s range. Their product line also supports epoxy molding compounds where low impurity levels are critical for optical clarity.
Typical buyers include foundries, ceramics manufacturers, composite material producers and paint formulators who need consistent particle size distribution and low impurity levels. Trade terms are not disclosed in the listing, so importers should request the minimum order quantity, lead time and Incoterms directly from the supplier. Confirming packaging size, freight options and payment conditions before placing an order ensures smooth logistics.

Sourcing Fused silica , fused quartz, silica powder from Sinoteng Silica Materials Technology (Jiangsu) Co., Ltd. - China Import Guide
Before placing an order, importers should verify the exact purity, Fe₂O₃ content, particle size distribution and mesh grade against a supplier‑issued certificate of analysis. Requesting a sample batch can confirm that the material meets the technical requirements of the intended application. Any custom specifications, such as alternative mesh sizes, should be confirmed in writing prior to production.
Logistics typically involve sea freight from the Xinyi port, with the supplier able to supply the product in 25 kg bags or 1 ton bulk bags. Buyers should clarify the preferred Incoterm, for example FOB Xinyi, and agree on a realistic lead time, which is often 30‑45 days after order confirmation. Payment terms are not disclosed, so negotiate a secure method such as a letter of credit or advance payment after inspection.
Quality assurance is essential for high‑purity silica; third‑party inspection agencies can verify particle size, moisture and iron content on arrival. Requesting test reports based on ASTM D 388 (particle size) and ASTM C 126 (moisture) helps ensure consistency. Maintaining proper documentation, including the material safety data sheet and certificate of origin, facilitates customs clearance and downstream processing.
