Cristobalite M3000/4000/6000
Lianyungang Changtong Silica Powder Co., Ltd. produces cristobalite silica flour in three fineness grades - M3000, M4000 and M6000 - tailored for high‑tech applications. All grades contain silicon dioxide above 99.5 % purity together with controlled trace oxides (Fe₂O₃ 0.03 %, Al₂O₃ 0.20 %, TiO₂ 0.02 %, K₂O 0.05 %, CaO 0.01 %). The grades differ primarily in particle size, with M3000 representing the finest powder and M6000 the coarsest, matching standard mesh classifications used in foundry and ceramic processes. The material exhibits a bright white colour typical of high‑purity cristobalite, facilitating colour‑critical manufacturing. In foundry casting the consistent particle distribution improves fluidity and reduces turbulence in mould pours. Advanced ceramics benefit from the low impurity levels that prevent discoloration during sintering. High‑grade paints and silicone rubber formulations rely on the stable chemical composition to maintain viscosity and cure characteristics. The product conforms to typical industry specifications for silica flour used in precision coating and refractory production. The company offers the flour in 25 kg bags and in 1 ton bulk bags, with container loads of 20‑25 ton per 20‑ft container. While the public listing does not state a fixed MOQ, buyers should confirm the minimum shipment size directly with the supplier. Payment terms, Incoterms and lead‑time are negotiated per order and must be clarified before contract finalisation.

Sourcing Cristobalite M3000/4000/6000 from Lianyungang Changtong Silica Powder Co., Ltd. - China Import Guide
Prior to placing an order, obtain a current Certificate of Analysis, recent sieve‑analysis data and a Material Safety Data Sheet to confirm that the silica flour meets your purity, particle‑size and safety requirements. Verify that the trace‑oxide levels align with your production tolerances and request any additional test reports that are relevant to your application.
Shipping from China typically departs from the Lianyungang port, with containers loaded according to the agreed Incoterms such as FOB or CIF. Confirm the exact freight forwarder, container loading plan and payment terms (e.g., T/T, L/C) before finalising the purchase. Lead‑time estimates are not published, so obtain a firm schedule from the supplier to align with your production timeline.
Quality assurance is best achieved by scheduling a third‑party inspection at the loading port or arranging on‑site sampling before shipment. Inspectors should verify particle‑size distribution, bulk density and moisture content against the supplied certificates. Retain all inspection and test documentation to support customs clearance and downstream quality control.
