Silicon Nitride(si3n4)
The offering is high‑purity Silicon Nitride (Si3N4) granules supplied by Shanghai Spark Advanced Material Co., Ltd. The material is marketed as having exceptional mechanical strength, high toughness and resistance to thermal shock, suitable for high‑temperature industrial use. Shanghai Spark notes that the granules are produced with consistent purity and controlled particle size distribution. The product complies with ISO and SGS certifications and is packed for bulk export.
In advanced ceramics, Si3N4 granules typically possess a purity of 99.9 % or higher and a particle size range of 5‑20 µm, which supports uniform sintering and predictable performance. Typical bulk density values are around 3.2 g/cm³ and flexural strength can reach 600‑900 MPa after densification. These characteristics make the granules a preferred feedstock for aerospace components, engine parts and refractory applications where wear resistance and thermal stability are critical. The supplier highlights that the granules are suitable for powder metallurgy and high‑temperature processing.
Shanghai Spark offers flexible bulk order quantities and can ship under FOB or CIF terms from its facility in the Chanba Ecological Zone, Xi’an, Shaanxi. Standard industrial packaging, such as sealed bulk bags within wooden pallets, is used to protect the granules during transport. Prospective buyers should confirm current certification documents, lead‑time estimates and payment conditions before finalising the transaction.

Sourcing Silicon Nitride(si3n4) from Shanghai Spark Advanced Material Co., Ltd - China Import Guide
When considering a purchase, first request the latest certificate of analysis and any relevant ISO or SGS test reports, covering purity, particle size and density. Verify that the granule specifications match your processing parameters and ask for a sample if possible. Confirm the supplier’s manufacturing capabilities and quality management system to mitigate the risk of receiving material that falls short of performance expectations.
Discuss shipping arrangements by agreeing on an Incoterm such as FOB Xi’an or CIF a nearby seaport, and obtain an estimated lead time for bulk bag preparation and loading. Payment terms are commonly negotiated on a letter of credit or advance basis; ensure that the supplier’s banking information is independently verified. Align these logistics details with your freight forwarder to avoid unexpected customs or transport issues.
Plan a pre‑shipment inspection that checks the integrity of the bulk bags, verifies the seal, and samples the granules for purity and particle size. Request the full set of certification documents, including material safety data sheets, to support customs clearance. Keeping detailed inspection records will help you maintain supplier performance oversight and streamline future import cycles.
