Fused Silica For Refractory/casting/ceramic
The product is fused silica with a stated purity of at least 99.5% SiO₂, supplied in both granular and powder forms for use in refractory, casting and advanced ceramic applications. It maintains structural integrity at temperatures exceeding 1700°C and exhibits a low coefficient of thermal expansion, which helps prevent cracking under rapid temperature changes. The supplier highlights the material's suitability for precision casting molds, kiln furniture and high‑temperature insulation, emphasizing its durability in harsh environments.
In the refractory industry typical purity levels for high‑grade fused silica are around 99.8% SiO₂, providing consistent performance across batches. Particle size is usually distributed between 0 and 150 µm, a range that balances flowability and packing density. Standard bulk density for this material is about 2.2 g/cm³, and typical thermal conductivity is 1.4 W/m·K at 1000°C, both of which influence design calculations for insulation and heat transfer. These values are considered standard for fused silica used in high‑temperature processes.
Foundries, steel plants and ceramics manufacturers are the main buyers, seeking material that can withstand extreme heat while maintaining dimensional stability. Trade discussions can address FOB or CIF terms, with minimum order quantities and payment methods such as a letter of credit or telegraphic transfer to be agreed directly with the supplier. Interested importers should request the specific grain‑size distribution and any applicable ISO certification before finalising a purchase.

Sourcing Fused Silica For Refractory/casting/ceramic from Chem & Size Minerals Limited - China Import Guide
Importers should first confirm the silica purity by obtaining a current certificate of analysis and verify the low thermal expansion coefficient with an accredited test report. It is also advisable to check that the material meets the ISO‑9001 standard claimed by the supplier and that serial‑number traceability is in place for batch tracking.
Logistics typically involve shipping from ports in Jiangsu Province, but the listing does not provide a specific lead time, so buyers must ask the supplier for an estimated production and delivery schedule. Discuss preferred Incoterms such as FOB or CIF, and arrange payment through a secure method like a letter of credit or telegraphic transfer after inspection.
For quality assurance, a third‑party inspection before loading is recommended, focusing on particle size distribution, bulk density and thermal conductivity measurements. Request the full set of commercial documents, including a commercial invoice, packing list and certificate of origin, to ensure smooth customs clearance and compliance with import regulations.
